* Supress convertion of zero hours to '12' for intervals when usingBruce Momjian2010-02-23
| | | | | | | | | | | | | | to_char with HH, e.g. to_char(interval '0d 0h 12m 44s', 'DD HH24 MI SS'); now returns: 00 00 12 44 not: 00 12 12 44
* Let's try forcing errno to zero before issuing fsync. The current buildfarmTom Lane2010-02-22
| | | | | results claiming EBADF seem improbable enough that I'm not convinced fsync is really returning that --- could it be failing to set errno at all?
* Adjust pg_fsync_writethrough so that it will set errno when failingTom Lane2010-02-22
| | | | | | | on a platform that doesn't support this operation. The former coding would allow an unrelated errno to be reported, which would be quite misleading. Not sure if this has anything to do with the current buildfarm failures, but it's certainly bogus as-is.

* Clean up handling of XactReadOnly and RecoveryInProgress checks.Tom Lane2010-02-20
| | | | | | | | | | | | | | | | | | Add some checks that seem logically necessary, in particular let's make real sure that HS slave sessions cannot create temp tables. (If they did they would think that temp tables belonging to the master's session with the same BackendId were theirs. We *must* not allow myTempNamespace to become set in a slave session.) Change setval() and nextval() so that they are only allowed on temp sequences in a read-only transaction. This seems consistent with what we allow for table modifications in read-only transactions. Since an HS slave can't have a temp sequence, this also provides a nicer cure for the setval PANIC reported by Erik Rijkers. Make the error messages more uniform, and have them mention the specific command being complained of. This seems worth the trifling amount of extra code, since people are likely to see such messages a lot more than before.
* Reduce the rescan cost estimate for Materialize nodes to cpu_operator_cost perTom Lane2010-02-19
| | | | | | | | | | | | | | | | tuple, instead of the former cpu_tuple_cost. It is sane to charge less than cpu_tuple_cost because Materialize never does any qual-checking or projection, so it's got less overhead than most plan node types. In particular, we want to have the same charge here as is charged for readout in cost_sort. That avoids the problem recently exhibited by Teodor wherein the planner prefers a useless sort over a materialize step in a context where a lot of rescanning will happen. The rescan costs should be just about the same for both node types, so make their estimates the same. Not back-patching because all of the current logic for rescan cost estimates is new in 9.0. The old handling of rescans is sufficiently not-sane that changing this in that structure is a bit pointless, and might indeed cause regressions.

* Small corrections to message output targets in pg_ctlPeter Eisentraut2010-02-19
| | | | | | | - The message "server stopped" should be affected by the -s option, just like "server started" already was. - The message "could not start server" should consistently go to stderr.
* Don't use O_DIRECT when writing WAL files if archiving or streaming isHeikki Linnakangas2010-02-19
| | | | | | | | | | enabled. Bypassing the kernel cache is counter-productive in that case, because the archiver/walsender process will read from the WAL file soon after it's written, and if it's not cached the read will cause a physical read, eating I/O bandwidth available on the WAL drive. Also, walreceiver process does unaligned writes, so disable O_DIRECT in walreceiver process for that reason too.

Furthermore the previous implementation could return nonexistent segment file name when the boundary is in segments that has "FE" suffix; We never use segments with "FF" suffix. Backpatch to 8.0, where hot backup was introduced. Reported by Fujii Masao.

* Volatile-ize all five places where we expect a PG_TRY block to restoreTom Lane2010-02-18
| | | | | | old memory context in plpython. Before only one of them was marked volatile, but per report from Zdenek Kotala, some compilers do the wrong thing here.
* Provide some rather hokey ways for EXPLAIN to print FieldStore and assignmentTom Lane2010-02-18
| | | | | | | | | | | | | | | | | | ArrayRef expressions that are not in the immediate context of an INSERT or UPDATE targetlist. Such cases never arise in stored rules, so ruleutils.c hadn't tried to handle them. However, they do occur in the targetlists of plans derived from such statements, and now that EXPLAIN VERBOSE tries to print targetlists, we need some way to deal with the case. I chose to represent an assignment ArrayRef as "array[subscripts] := source", which is fairly reasonable and doesn't omit any information. However, FieldStore is problematic because the planner will fold multiple assignments to fields of the same composite column into one FieldStore, resulting in a structure that is hard to understand at all, let alone display comprehensibly. So in that case I punted and just made it print the source expression(s). Backpatch to 8.4 --- the lack of functionality exists in older releases, but doesn't seem to be important for lack of anything that would call it.
* Fix ExecEvalArrayRef to pass down the old value of the array element or sliceTom Lane2010-02-18
| | | | | | | | | | | | | being assigned to, in case the expression to be assigned is a FieldStore that would need to modify that value. The need for this was foreseen some time ago, but not implemented then because we did not have arrays of composites. Now we do, but the point evidently got overlooked in that patch. Net result is that updating a field of an array element doesn't work right, as illustrated if you try the new regression test on an unpatched backend. Noted while experimenting with EXPLAIN VERBOSE, which has also got some issues in this area. Backpatch to 8.3, where arrays of composites were introduced.
* Fix pq_getbyte_if_available() function. It was confused on what itHeikki Linnakangas2010-02-18

* Force READY portals into FAILED state when a transaction or subtransactionTom Lane2010-02-18
| | | | | | | | | | | is aborted, if they were created within the failed xact. This prevents ExecutorEnd from being run on them, which is a good idea because they may contain references to tables or other objects that no longer exist. In particular this is hazardous when auto_explain is active, but it's really rather surprising that nobody has seen an issue with this before. I'm back-patching this to 8.4, since that's the first version that contains auto_explain or an ExecutorEnd hook, but I wonder whether we shouldn't back-patch further.
* Fix up pg_dump's treatment of large object ownership and ACLs. We now emitTom Lane2010-02-18
| | | | | | | | | | a separate archive entry for each BLOB, and use pg_dump's standard methods for dealing with its ownership, ACL if any, and comment if any. This means that switches like --no-owner and --no-privileges do what they're supposed to. Preliminary testing says that performance is still reasonable even with many blobs, though we'll have to see how that shakes out in the field. KaiGai Kohei, revised by me

* Support new syntax and improve handling of parentheses in psql tab-completion.Itagaki Takahiro2010-02-17
| | | | | | | | | | | | Newly supported syntax are: - ALTER {TABLE|INDEX|TABLESPACE} {SET|RESET} with options - ALTER TABLE ALTER COLUMN {SET|RESET} with options - ALTER TABLE ALTER COLUMN SET STORAGE - CREATE INDEX CONCURRENTLY - CREATE INDEX ON (without name) - CREATE INDEX ... USING with pg_am.amname instead of hard-corded names - CREATE TRIGGER with events - DROP AGGREGATE function with arguments
* When updating ShmemVariableCache from a checkpoint record, be sure to setTom Lane2010-02-17
| | | | | | | | | | all the values derived from oldestXid, not just that field. Brain fade in one of my patches associated with flat file removal, exposed by a report from Fujii Masao. With this change, xidVacLimit should always be valid, so remove a couple of bits of complexity associated with the previous assumption that sometimes it wouldn't get set right away.

* Make NOTIFY_PAYLOAD_MAX_LENGTH depend explicitly on BLCKSZ andTom Lane2010-02-17
| | | | | | NAMEDATALEN, so this code doesn't go nuts with smaller than default BLCKSZ or larger than default NAMEDATALEN. The standard value is still exactly 8000.
* Replace the pg_listener-based LISTEN/NOTIFY mechanism with an in-memory queue.Tom Lane2010-02-16
| | | | | | | | | | | | In addition, add support for a "payload" string to be passed along with each notify event. This implementation should be significantly more efficient than the old one, and is also more compatible with Hot Standby usage. There is not yet any facility for HS slaves to receive notifications generated on the master, although such a thing is possible in future. Joachim Wieland, reviewed by Jeff Davis; also hacked on by me.
* Add query text to auto_explain output.Andrew Dunstan2010-02-16

* Clean up package namespace use and use of Safe in plperl.Andrew Dunstan2010-02-16
| | | | | | | | | | | | | | | Prevent use of another buggy version of Safe.pm. Only register the exit handler if we have successfully created an interpreter. Change log level of perl warnings from NOTICE to WARNING. The infrastructure is there if in future we decide to allow DBAs to specify extra modules that will be allowed in trusted code. However, for now the relevant variables are declared as lexicals rather than as package variables, so that they are not (or should not be) accessible. Mostly code from Tim Bunce, reviewed by Alex Hunsaker, with some tweaks by me.

* Add emulation of non-blocking sockets to the win32 socket/signal layer,Magnus Hagander2010-02-16
| | | | | | | | | and use this in pq_getbyte_if_available. It's only a limited implementation which swithes the whole emulation layer no non-blocking mode, but that's enough as long as non-blocking is only used during a short period of time, and only one socket is accessed during this time.
