* pg_upgrade: prevent automatic oid assignmentBruce Momjian2014-08-25
| | | | | | | | | | Prevent automatic oid assignment when in binary upgrade mode. Also throw an error when contrib/pg_upgrade_support functions are called when not in binary upgrade mode. This prevent automatically-assigned oids from conflicting with later pre-assigned oids coming from the old cluster. It also makes sure oids are preserved in call important cases.

* Revert XactLockTableWait context setup in conditional multixact waitAlvaro Herrera2014-08-25
| | | | | | | | | There's no point in setting up a context error callback when doing conditional lock acquisition, because we never actually wait and so the user wouldn't be able to see the context message anywhere. In fact, this is more in line with what ConditionalXactLockTableWait is doing. Backpatch to 9.4, where this was added.
* Use newly added InvalidCommandId instead of 0Alvaro Herrera2014-08-25
| | | | | | | | | The symbol was added by 71901ab6d; the original code was introduced by 6868ed749. Development of both overlapped which is why we apparently failed to notice. This is a (very slight) behavior change, so I'm not backpatching this to 9.4 for now, even though the symbol does exist there.
* DefineType: return base type OID, not its arrayAlvaro Herrera2014-08-25
| | | | | | Event triggers want to know the OID of the interesting object created, which is the main type. The array created as part of the operation is just a subsidiary object which is not of much interest.
* Have CREATE TABLE AS and REFRESH return an OIDAlvaro Herrera2014-08-25
| | | | | | Other DDL commands are already returning the OID, which is required for future additional event trigger work. This is merely making these commands in line with the rest of utility command support.

* Fix another ancient memory-leak bug in relcache.c.Tom Lane2014-08-24
| | | | | | | | | | | | | | | | | | | | | | | | CheckConstraintFetch() leaked a cstring in the caller's context for each CHECK constraint expression it copied into the relcache. Ordinarily that isn't problematic, but it can be during CLOBBER_CACHE testing because so many reloads can happen during a single query; so complicate the code slightly to allow freeing the cstring after use. Per testing on buildfarm member barnacle. This is exactly like the leak fixed in AttrDefaultFetch() by commit 078b2ed291c758e7125d72c3a235f128d40a232b. (Yes, this time I did look for other instances of the same coding pattern :-(.) Like that patch, no back-patch, since it seems unlikely that there's any problem except under very artificial test conditions. BTW, it strikes me that both of these places would require further work comparable to commit ab8c84db2f7af008151b848cf1d6a4672a39eecd, if we ever supported defaults or check constraints on system catalogs: they both assume they are copying into an empty relcache data structure, and that conceivably wouldn't be the case during recursive reloading of a system catalog. This does not seem worth worrying about for the moment, since there is no near-term prospect of supporting any such thing. So I'll just note the possibility for the archives' sake.
* doc: Improve pg_restore help outputPeter Eisentraut2014-08-23
| | | | | | Add a note that some options can be specified multiple times to select multiple objects to restore. This replaces the somewhat confusing use of plurals in the option descriptions themselves.
* Implement ALTER TABLE .. SET LOGGED / UNLOGGEDAlvaro Herrera2014-08-22
| | | | | | | | | | | | This enables changing permanent (logged) tables to unlogged and vice-versa. (Docs for ALTER TABLE / SET TABLESPACE got shuffled in an order that hopefully makes more sense than the original.)

* Fix corner-case behaviors in JSON/JSONB field extraction operators.Tom Lane2014-08-22
| | | | | | | | | | | | | | | | | | | | | Cause the path extraction operators to return their lefthand input, not NULL, if the path array has no elements. This seems more consistent since the case ought to correspond to applying the simple extraction operator (->) zero times. Cause other corner cases in field/element/path extraction to return NULL rather than failing. This behavior is arguably more useful than throwing an error, since it allows an expression index using these operators to be built even when not all values in the column are suitable for the extraction being indexed. Moreover, we already had multiple inconsistencies between the path extraction operators and the simple extraction operators, as well as inconsistencies between the JSON and JSONB code paths. Adopt a uniform rule of returning NULL rather than throwing an error when the JSON input does not have a structure that permits the request to be satisfied. Back-patch to 9.4. Update the release notes to list this as a behavior change since 9.3.
* Fix comment in pg_basebackup.Heikki Linnakangas2014-08-22
| | | | | | The option is called --tablespace-mapping, not --tablespace. Amit Kapila
* Change the way pg_basebackup's tablespace mapping is implemented.Heikki Linnakangas2014-08-22
| | | | | | | | | | | | | | | | Previously, we would first create the symlinks the way they are in the original system, and at the end replace them with the mapped symlinks. That never really made much sense, so now we create the symlink pointing to the correct location to begin with, so that there's no need to fix them at the end. The old coding didn't work correctly on Windows, because Windows junction points look more like directories than files, and ought to be removed with rmdir rather than unlink. Also, it incorrectly used "%d" rather than "%u" to print an Oid, but that's gone now. Report and patch by Amit Kapila, with minor changes by me. Reviewed by MauMau. Backpatch to 9.4, where the --tablespace feature was added.

* Rework 'MOVE ALL' to 'ALTER .. ALL IN TABLESPACE'Stephen Frost2014-08-21
| | | | | | | | | | | | As 'ALTER TABLESPACE .. MOVE ALL' really didn't change the tablespace but instead changed objects inside tablespaces, it made sense to rework the syntax and supporting functions to operate under the 'ALTER (TABLE|INDEX|MATERIALIZED VIEW)' syntax and to be in tablecmds.c. Pointed out by Alvaro, who also suggested the new syntax. Back-patch to 9.4.
* Add #define INT64_MODIFIER for the printf length modifier for 64-bit ints.Heikki Linnakangas2014-08-21
| | | | | | | We have had INT64_FORMAT and UINT64_FORMAT for a long time, but that's not good enough if you want something more exotic, like "%20lld". Abhijit Menon-Sen, per Andres Freund's suggestion.
* More regression test cases for json/jsonb extraction operators.Tom Lane2014-08-20
| | | | | | | Cover some cases I omitted before, such as null and empty-string elements in the path array. This exposes another inconsistency: json_extract_path complains about empty path elements but jsonb_extract_path does not.
* Fix core dump in jsonb #> operator, and add regression test cases.Tom Lane2014-08-20
| | | | | | | | | | | | | | | | | jsonb's #> operator segfaulted (dereferencing a null pointer) if the RHS was a zero-length array, as reported in bug #11207 from Justin Van Winkle. json's #> operator returns NULL in such cases, so for the moment let's make jsonb act likewise. Also add a bunch of regression test queries memorializing the -> and #> operators' behavior for this and other corner cases. There is a good argument for changing some of these behaviors, as they are not very consistent with each other, and throwing an error isn't necessarily a desirable behavior for operators that are likely to be used in indexes. However, everybody can agree that a core dump is the Wrong Thing, and we need test cases even if we decide to change their expected output later.
* Use comma+space as the separator in the default search_path.Heikki Linnakangas2014-08-20
| | | | | | | | While the space is optional, it seems nicer to be consistent with what you get if you do "SET search_path=...". SET always normalizes the separator to be comma+space. Christoph Martin
* Revert "Fix bug in checking of IDENTIFY_SYSTEM result."Fujii Masao2014-08-19
| | | | | | | | | | | | | | This reverts commit 083d29c65b7897f90c70e6dc0a4240a5fa75c8f2. The commit changed the code so that it causes an errors when IDENTIFY_SYSTEM returns three columns. But which prevents us from using the replication-related utilities against the server with older version. This is not what we want. For that compatibility, we allow the utilities to receive three columns as the result of IDENTIFY_SYSTEM eventhough it actually returns four columns in 9.4 or later. Pointed out by Andres Freund.
* Fix bug in checking of IDENTIFY_SYSTEM result.Fujii Masao2014-08-19
| | | | | | | | | | | | | 5a991ef8692ed0d170b44958a81a6bd70e90585 added new column into the result of IDENTIFY_SYSTEM command. But it was not reflected into several codes checking that result. Specifically though the number of columns in the result was increased to 4, it was still compared with 3 in some replication codes. Back-patch to 9.4 where the number of columns in IDENTIFY_SYSTEM result was increased. Report from Michael Paquier
* Install libpq DLL with $(INSTALL_SHLIB).Noah Misch2014-08-18
| | | | | | | Programs need execute permission on a DLL file to load it. MSYS "install" ignores the mode argument, and our Cygwin build statically links libpq into programs. That explains the lack of buildfarm trouble. Back-patch to 9.0 (all supported versions).
* Finish adding file version information to installed Windows binaries.Noah Misch2014-08-18

* Replace a few strncmp() calls with strlcpy().Noah Misch2014-08-18
| | | | | | | | | | | strncmp() is a specialized API unsuited for routine copying into fixed-size buffers. On a system where the length of a single filename can exceed MAXPGPATH, the pg_archivecleanup change prevents a simple crash in the subsequent strlen(). Few filesystems support names that long, and calling pg_archivecleanup with untrusted input is still not a credible use case. Therefore, no back-patch. David Rowley

* Reorganize functions in be-secure-openssl.cHeikki Linnakangas2014-08-18
| | | | | | | | | Move the functions within the file so that public interface functions come first, followed by internal functions. Previously, be_tls_write was first, then internal stuff, and finally the rest of the public interface, which clearly didn't make much sense. Per Andres Freund's complaint.
* Use ISO 8601 format for dates converted to JSON, too.Tom Lane2014-08-17
| | | | | | | | Commit f30015b6d794c15d52abbb3df3a65081fbefb1ed made this happen for timestamp and timestamptz, but it seems pretty inconsistent to not do it for simple dates as well. (In passing, I re-pgindent'd json.c.)
* Fix bogus return macros in range_overright_internal().Tom Lane2014-08-16
| | | | | | | | | PG_RETURN_BOOL() should only be used in functions following the V1 SQL function API. This coding accidentally fails to fail since letting the compiler coerce the Datum representation of bool back to plain bool does give the right answer; but that doesn't make it a good idea. Back-patch to older branches just to avoid unnecessary code divergence.
* Add opr_sanity queries to inspect commutator/negator links more closely.Tom Lane2014-08-16
| | | | | | | | Make lists of the names of all operators that are claimed to be commutator pairs or negator pairs. This is analogous to the existing queries that make lists of all operator names appearing in particular opclass strategy slots. Unexpected additions to these lists are likely to be mistakes; had we had these queries in place before, bug #11178 might've been prevented.
* Fix bogus commutator/negator links for JSONB containment operators.Tom Lane2014-08-16
| | | | | | | | | | | | <@ and @> are each other's commutators, but they were incorrectly marked as being each other's negators instead. (This was actually questioned in a comment in the original commit, but nobody followed through :-(.) Per bug #11178 from Christian Pronovost. In passing, fix some JSONB operator descriptions that were randomly different from the phrasing of every other similar description. catversion bump for pg_catalog contents change.

* Set shared library path for in-tree TAP testsPeter Eisentraut2014-08-15
| | | | | | When the TAP tests are run in-tree (make check), set the shared library path using the appropriate environment variable, using a logic similar to pg_regress, so that the right libraries are used.
* Add sortsupport routines for text.Robert Haas2014-08-14

* Fix help message in pg_ctl.Fujii Masao2014-08-14
| | | | | | | | | Previously the help message described that -m is an option for "stop", "restart" and "promote" commands in pg_ctl. But actually that's not an option for "promote". So this commit fixes that incorrect description in the help message. Back-patch to 9.3 where the incorrect description was added.

* Prevent memory leaks in parseRelOptions().Tom Lane2014-08-13
| | | | | | | | | | | | | | | | parseRelOptions() tended to leak memory in the caller's context. Most of the time this doesn't really matter since the caller's context is at most query-lifespan, and the function won't be invoked very many times. However, when testing with CLOBBER_CACHE_RECURSIVELY, the same relcache entry can get rebuilt a *lot* of times in one query, leading to significant intraquery memory bloat if it has any reloptions. Noted while investigating a related report from Tomas Vondra. In passing, get rid of some Asserts that are redundant with the one done by deconstruct_array(). As with other patches to avoid leaks in CLOBBER_CACHE testing, it doesn't really seem worth back-patching this.
* Prevent memory leaks in RelationGetIndexList, RelationGetIndexAttrBitmap.Tom Lane2014-08-13
| | | | | | | | | | | | | | | | | When replacing rd_indexlist, rd_indexattr, etc, we neglected to pfree any old value of these fields. Under ordinary circumstances, the old value would always be NULL, so this seemed reasonable enough. However, in cases where we're rebuilding a system catalog's relcache entry and another cache flush occurs on that same catalog meanwhile, it's possible for the field to not be NULL when we return to the outer level, because we already refilled it while recovering from the inner flush. This leads to a fairly small session-lifespan leak in CacheMemoryContext. In real-world usage the leak would be too small to notice; but in testing with CLOBBER_CACHE_RECURSIVELY the leakage can add up to the point of causing OOM failures, as reported by Tomas Vondra. The issue has been there a long time, but it only seems worth fixing in HEAD, like the previous fix in this area (commit 078b2ed291c758e7).
* Expose -S option in pg_receivexlog.Fujii Masao2014-08-13
| | | | | | | | | | | | This option is equivalent to --slot option which pg_receivexlog has already supported, which specifies the replication slot to use for WAL streaming. pg_recvlogical has already supported both options, and this commit makes pg_receivexlog consistent with pg_recvlogical regarding the slot option. Back-patch to 9.4 where the slot option was added. Michael Paquier
* pg_recvlogical message and code improvements.Andres Freund2014-08-12
| | | | | | | | | | | | Some error messages complained about --init and --stop being used whereas the --create and --drop are the correct verbs. Fix that. Also a XLogRecPtr was tested in a boolean fashion instead of being compared to InvalidXLogRecPtr. Backpatch to 9.4 where pg_recvlogical was introduced. Michael Paquier
* Be less aggressive in asking for feedback of logical walsender clients.Andres Freund2014-08-12
| | | | | | | | | | | | | | | | | | When doing logical decoding using START_LOGICAL_REPLICATION in a walsender process the walsender sometimes was sending out keepalive messages too frequently. Asking for feedback every time. WalSndWaitForWal() sends out keepalive messages when it's waiting for new WAL to be generated locally when it sees that the remote side hasn't yet flushed WAL up to the local position. That generally is good but causes problems if the remote side only writes but doesn't flush changes yet. So check for both remote write and flush position. Additionally we've asked for feedback to the keepalive message which isn't warranted when waiting for WAL in contrast to preventing timeouts because of wal_sender_timeout. Complaint and patch by Steve Singer.
* Change first call of ProcessConfigFile so as to process only data_directory.Fujii Masao2014-08-12
| | | | | | | | | | | | | | | | | | | | | | | When both postgresql.conf and postgresql.auto.conf have their own entry of the same parameter, PostgreSQL uses the entry in postgresql.auto.conf because it appears last in the configuration scan. IOW, the other entries which appear earlier are ignored. But, previously, ProcessConfigFile() detected the invalid settings of even those unused entries and emitted the error messages complaining about them, at postmaster startup. Complaining about the entries to ignore is basically useless. This problem happened because ProcessConfigFile() was called twice at postmaster startup and the first call read only postgresql.conf. That is, the first call could check the entry which might be ignored eventually by the second call which read both postgresql.conf and postgresql.auto.conf. To work around the problem, this commit changes ProcessConfigFile so that its first call processes only data_directory and the second one does all the entries. It's OK to process data_directory in the first call because it's ensured that data_directory doesn't exist in postgresql.auto.conf. Back-patch to 9.4 where postgresql.auto.conf was added. Patch by me. Review by Amit Kapila
