* Fix memory leak for file name if expect file name contains a dot, perBruce Momjian2009-01-08
| | | | report from dvice_null@yahoo.com.
* A couple further reloptions improvements, per KaiGai Kohei: add a validationAlvaro Herrera2009-01-08
| | | | | | function to the string type and add a couple of macros for string handling. In passing, fix an off-by-one bug of mine.

* Add comment about why BETWEEN uses operator strings and not opclasses,Bruce Momjian2009-01-07
| | | | with URL pointing to email discussion.
* Create a third option named "partition" for constraint_exclusion, and make itTom Lane2009-01-07
| | | | | | | | | the default. This setting enables constraint exclusion checks only for appendrel members (ie, inheritance children and UNION ALL arms), which are the cases in which constraint exclusion is most likely to be useful. Avoiding the overhead for simple queries that are unlikely to benefit should bring the cost down to the point where this is a reasonable default setting. Per today's discussion.
* Have current_query() use ActivePortal->sourceText rather thanBruce Momjian2009-01-07
| | | | | debug_query_string; this allows current_query() to be more accurate; docs updated; per idea from Tom
* Insert conditional SPI_push/SPI_pop calls into InputFunctionCall,Tom Lane2009-01-07
| | | | | | | | | | | | | | | | | | | | OutputFunctionCall, and friends. This allows SPI-using functions to invoke datatype I/O without concern for the possibility that a SPI-using function will be called (which could be either the I/O function itself, or a function used in a domain check constraint). It's a tad ugly, but not nearly as ugly as what'd be needed to make this work via retail insertion of push/pop operations in all the PLs. This reverts my patch of 2007-01-30 that inserted some retail SPI_push/pop calls into plpgsql; that approach only fixed plpgsql, and not any other PLs. But the other PLs have the issue too, as illustrated by a recent gripe from Christian Schröder. Back-patch to 8.2, which is as far back as this solution will work. It's also as far back as we need to worry about the domain-constraint case, since earlier versions did not attempt to check domain constraints within datatype input. I'm not aware of any old I/O functions that use SPI themselves, so this should be sufficient for a back-patch.
* Add comment that it is difficult to access the more accurateBruce Momjian2009-01-07

* Fix executor/spi.h to follow our usual conventions for include files, ie,Tom Lane2009-01-07
| | | | | | | | | not include postgres.h nor anything else it doesn't directly need. Add #includes to calling files as needed to compensate. Per my proposal of yesterday. This should be noted as a source code change in the 8.4 release notes, since it's likely to require changes in add-on modules.
* Add hba parameter include_realm to krb5, gss and sspi authentication, usedMagnus Hagander2009-01-07
| | | | | | to pass the full username@realm string to the authentication instead of just the username. This makes it possible to use pg_ident.conf to authenticate users from multiple realms as different database users.
* Allow krb_realm (krb5, gssapi and sspi) and krb_server_hostname (krb5 only)Magnus Hagander2009-01-07
| | | | | authentication options to be set in pg_hba.conf on a per-line basis, to override the defaults set in postgresql.conf.
* Don't require pqGetHomeDirectory to succeed if the user has specifiedMagnus Hagander2009-01-07
| | | | | | hardcoded paths for SSL rootcert/crl/clientcert/key. As noted by Andrew Chernow
* Make the log output of 'vxid' between csvlog and stderr/syslogBruce Momjian2009-01-07
| | | | | | | | consistent. Currently, in csvlog, vxid of an auxiliary process isn't displayed. On the other hand, in stderr/syslog, invalid vxid (-1/0) of that is displayed. Fujii Masao

* Change a couple of ill-advised uses of INFO elog level to WARNINGs; inTom Lane2009-01-06
| | | | | | | particular this allows EmitWarningsOnPlaceholders messages to show up in the postmaster log by default. Update elog.h comment to make it clearer what INFO is for, and fix one example in the SGML docs that was misusing it. Per my gripe of yesterday.
* Revert the default toast compression strategy to the former behaviorTom Lane2009-01-06
| | | | | where there's no limit on the size of datum we'll try to compress. Other 8.4 tweaks to the behavior remain in place. Per discussion.
* Doesn't seem like a good idea to be doing AC_CHECK_SIZEOF(void *) so muchTom Lane2009-01-06
| | | | | earlier than all the other sizeof checks, and it certainly fails to follow the order suggested at the file head. Rearrange.
* Fix logic in lazy vacuum to decide if it's worth trying to truncate the heap.Heikki Linnakangas2009-01-06
| | | | | | | | If the table was smaller than REL_TRUNCATE_FRACTION (= 16) pages, we always tried to acquire AccessExclusiveLock on it even if there was no empty pages at the end. Report by Simon Riggs. Back-patch all the way to 7.4.

* Add some comments about why function parameter default expressions areTom Lane2009-01-06
| | | | restricted.
* Fix an oversight in the function-default-arguments patch: after adding someTom Lane2009-01-06
| | | | | | | default expressions to a function call, eval_const_expressions must recurse on those expressions. Else they don't get simplified, and in particular we fail to insert additional default arguments if any functions needing defaults are in there. Per report from Rushabh Lathia.
* Change the reloptions machinery to use a table-based parser, and provideAlvaro Herrera2009-01-05
| | | | | | | | a more complete framework for writing custom option processing routines by user-defined access methods. Catalog version bumped due to the general API changes, which are going to affect user-defined "amoptions" routines.
* Add a --role option to pg_dump, pg_dumpall, and pg_restore. This allowsTom Lane2009-01-05
| | | | | | | | | | | performing dumps and restores in accordance with a security policy that forbids logging in directly as superuser, but instead specifies that you should log into an admin account and then SET ROLE to the superuser. In passing, clean up some ugly and mostly-broken code for quoting shell arguments in pg_dumpall. Benedek László, with some help from Tom Lane
* Quiet repeated "loaded library" messages from child backends that are justTom Lane2009-01-05

* When cross-compiling, allow and require an external zic program to be usedPeter Eisentraut2009-01-05
| | | | | | when --with-system-tzdata is not used. initial patch by Richard Evans
* Fix for cross-compilation between mingw32 and something else. The choicePeter Eisentraut2009-01-05

* Add contrib/pg_stat_statements for server-wide tracking of statement executionTom Lane2009-01-04
| | | | | | statistics. Takahiro Itagaki
* Add a pg_encoding_mbcliplen() function that is just like pg_mbcliplen()Tom Lane2009-01-04
| | | | | | | | except the caller can specify the encoding to work in; this will be needed for pg_stat_statements. In passing, do some marginal efficiency hacking and clean up some comments. Also, prevent the single-byte-encoding code path from fetching one byte past the stated length of the string (this last is a bug that might need to be back-patched at some point).
* Fix embarrassing bug in recent smgr refactoring patch: WAL records shouldHeikki Linnakangas2009-01-04
| | | | | be written for *non*-temp tables only. Report and test case by Mark Kirkwood and Simon Riggs.
* Allow loadable modules to create PGC_POSTMASTER GUC variables, but onlyTom Lane2009-01-03
| | | | | | when loaded via shared_preload_libraries. Needed for support of pg_stat_statements, or pretty much anything else that wants a GUC to control size of a shared memory allocation.
* Create a "shmem_startup_hook" to be called at the end of shared memoryTom Lane2009-01-03
| | | | | | | | | | | | | initialization, to give loadable modules a reasonable place to perform creation of any shared memory areas they need. This is the logical conclusion of our previous creation of RequestAddinShmemSpace() and RequestAddinLWLocks(). We don't need an explicit shmem_shutdown_hook, because the existing on_shmem_exit and on_proc_exit mechanisms serve that need. Also, adjust SubPostmasterMain so that libraries that got loaded into the postmaster will be loaded into all child processes, not only regular backends. This improves consistency with the non-EXEC_BACKEND behavior, and might be necessary for functionality for some types of add-ons.
* Include a pointer to the query's source text in QueryDesc structs. This isTom Lane2009-01-02
| | | | | | | practically free given prior 8.4 changes in plancache and portal management, and it makes it a lot easier for ExecutorStart/Run/End hooks to get at the query text. Extracted from Itagaki Takahiro's pg_stat_statements patch, with minor editorialization.
