* In postgresql.conf.sample, use on/off rather than true/false.Robert Haas2010-07-27
| | | | | | | We used to be consistent about this, but my recent patch to add a restart_after_crash GUC failed to follow the existing convention. Report and patch from Fujii Masao.

* Add more checks against altering typed tablesPeter Eisentraut2010-07-23
| | | | | | | | - Prohibit altering column type - Prohibit changing inheritance - Move checks from Exec to Prep phases in ALTER TABLE code backpatched to 9.0
* Avoid deep recursion when assigning XIDs to multiple levels of subxacts.Robert Haas2010-07-23
| | | | | | Backpatch to 8.0. Andres Freund, with cleanup and adjustment for older branches by me.

* Add options to force quoting of all identifiers.Robert Haas2010-07-22
| | | | | | | | | | I've added a quote_all_identifiers GUC which affects the behavior of the backend, and a --quote-all-identifiers argument to pg_dump and pg_dumpall which sets the GUC and also affects the quoting done internally by those applications. Design by Tom Lane; review by Alex Hunsaker; in response to bug #5488 filed by Hartmut Goebel.
* Centralize DML permissions-checking logic.Robert Haas2010-07-22
| | | | | | | | | | | | Remove bespoke code in DoCopy and RI_Initial_Check, which now instead fabricate call ExecCheckRTPerms with a manufactured RangeTblEntry. This is intended to make it feasible for an enhanced security provider to actually make use of ExecutorCheckPerms_hook, but also has the advantage that RI_Initial_Check can allow use of the fast-path when column-level but not table-level permissions are present. KaiGai Kohei. Reviewed (in an earlier version) by Stephen Frost, and by me. Some further changes to the comments by me.
* CVS test: please ignoreBruce Momjian2010-07-20
| | | | Does modification just of CVS tag text cause an empty CVS diff for the commit?
* Properly replay CREATE TABLESPACE during crash recovery by deletingBruce Momjian2010-07-20
| | | | | | | | directory/symlink before creation. Report from Tom Lane. Backpatch to 9.0.
* Add restart_after_crash GUC.Robert Haas2010-07-20
| | | | | | | | | | | Normally, we automatically restart after a backend crash, but in some cases when PostgreSQL is invoked by clusterware it may be desirable to suppress this behavior, so we provide an option which does this. Since no existing GUC group quite fits, create a new group called "error handling options" for this and the previously undocumented GUC exit_on_error, which is now documented. Review by Fujii Masao.
* Change the default value of standard_conforming_strings to on.Robert Haas2010-07-20
| | | | | This change should be publicized to driver maintainers at once and release-noted as an incompatibility with previous releases.
* Remove unnecessary "Not safe to send CSV data" complaint from elog.c's fallbackTom Lane2010-07-18
| | | | | | | | | path when CSV logging is configured but not yet operational. It's sufficient to send the message to stderr, as we were already doing, and the "Not safe" gripe has already confused at least two core members ... Backpatch to 9.0, but not further --- doesn't seem appropriate to change this behavior in stable branches.
* Allow ORDER BY/GROUP BY/etc items to match targetlist items regardless ofTom Lane2010-07-18
| | | | | | | | | | | | | | | | | any implicit casting previously applied to the targetlist item. This is reasonable because the implicit cast, by definition, wasn't written by the user; so we are preserving the expected behavior that ORDER BY items match textually equivalent tlist items. The case never arose before because there couldn't be any implicit casting of a top-level SELECT item before we process ORDER BY etc. But now it can arise in the context of aggregates containing ORDER BY clauses, since the "targetlist" is the already-casted list of arguments for the aggregate. The net effect is that the datatype used for ORDER BY/DISTINCT purposes is the aggregate's declared input type, not that of the original input column; which is a bit debatable but not horrendous, and to do otherwise would require major rework that doesn't seem justified. Per bug #5564 from Daniel Grace. Back-patch to 9.0 where aggregate ORDER BY was implemented.
* Simplify missing tablespace replay error hint message, but only in HEADBruce Momjian2010-07-18
| | | | so we don't need to re-translate for 9.0.
* Add a log_file_mode GUC that allows control of the file permissions set onTom Lane2010-07-16
| | | | | | | | | log files created by the syslogger process. In passing, make unix_file_permissions display its value in octal, same as log_file_mode now does. Martin Pihlak
* Add support for dividing money by money (yielding a float8 result) and forTom Lane2010-07-16
| | | | | | casting between money and numeric. Andy Balholm, reviewed by Kevin Grittner
* Remove a sanity check in the exclusion-constraint code that prevented usersTom Lane2010-07-16
| | | | | | | | | | | from defining non-self-conflicting constraints. Jeff Davis Note: I (tgl) objected to removing this check in 9.0 on the grounds that it was an important sanity check in new, poorly tested code. However, it should be all right to remove it for 9.1, since we'll get field testing from the 9.0 branch.
* Remove duplicate code in DefineOpFamily().Tom Lane2010-07-16
| | | | | | | The code was probably meant to be this way all along, since the subroutine CreateOpFamily previously had only one caller. But it wasn't. KaiGai Kohei
* Teach EXPLAIN to print PARAM_EXEC Params as the referenced expressions,Tom Lane2010-07-13
| | | | | | | | | | | | | | | | rather than just $N. This brings the display of nestloop-inner-indexscan plans back to where it's been, and incidentally improves the display of SubPlan parameters as well. In passing, simplify the EXPLAIN code by having it deal primarily in the PlanState tree rather than separately searching Plan and PlanState trees. This is noticeably cleaner for subplans, and about a wash elsewhere. One small difference from previous behavior is that EXPLAIN will no longer qualify local variable references in inner-indexscan plan nodes, since it no longer sees such nodes as possibly referencing multiple tables. Vars referenced through PARAM_EXEC Params are still forcibly qualified, though, so I don't think the display is any more confusing than before. Adjust a couple of examples in the documentation to match this behavior.
* Oops, in the previous fix to prevent a cursor that's being used in a FORHeikki Linnakangas2010-07-13
| | | | | | | | | loop from being dropped, I missed subtransaction cleanup. Pinned portals must be dropped at subtransaction cleanup just as they are at main transaction cleanup. Per bug #5556 by Robert Walker. Backpatch to 8.0, 7.4 didn't have subtransactions.
* Make NestLoop plan nodes pass outer-relation variables into their innerTom Lane2010-07-12
| | | | | | | | | | | | relation using the general PARAM_EXEC executor parameter mechanism, rather than the ad-hoc kluge of passing the outer tuple down through ExecReScan. The previous method was hard to understand and could never be extended to handle parameters coming from multiple join levels. This patch doesn't change the set of possible plans nor have any significant performance effect, but it's necessary infrastructure for future generalization of the concept of an inner indexscan plan. ExecReScan's second parameter is now unused, so it's removed.
* Avoid an Assert failure in deconstruct_array() by making get_attstatsslot()Tom Lane2010-07-09
| | | | | | | | | | | | | | | | use the actual element type of the array it's disassembling, rather than trusting the type OID passed in by its caller. This is needed because sometimes the planner passes in a type OID that's only binary-compatible with the target column's type, rather than being an exact match. Per an example from Bernd Helmle. Possibly we should refactor get_attstatsslot/free_attstatsslot to not expect the caller to supply type ID data at all, but for now I'll just do the minimum-change fix. Back-patch to 7.4. Bernd's test case only crashes back to 8.0, but since these subroutines are the same in 7.4, I suspect there may be variant cases that would crash 7.4 as well.
* Fix ruleutils' get_variable() to print something useful for Vars referencingTom Lane2010-07-09
| | | | | | | | | | resjunk outputs of subquery tlists, instead of throwing an error. Per bug #5548 from Daniel Grace. We might at some point find we ought to back-patch this further than 9.0, but I think that such Vars can only occur as resjunk members of upper-level tlists, in which case the problem can't arise because prior versions didn't print resjunk tlist items in EXPLAIN VERBOSE.
* Add a hook in ExecCheckRTPerms().Robert Haas2010-07-09
| | | | | | | | | | | This hook allows a loadable module to gain control when table permissions are checked. It is expected to be used by an eventual SE-PostgreSQL implementation, but there are other possible applications as well. A sample contrib module can be found in the archives at: http://archives.postgresql.org/pgsql-hackers/2010-05/msg01095.php Robert Haas and Stephen Frost

* Fix "cannot handle unplanned sub-select" error that can occur when aTom Lane2010-07-08
| | | | | | | | | sub-select contains a join alias reference that expands into an expression containing another sub-select. Per yesterday's report from Merlin Moncure and subsequent off-list investigation. Back-patch to 7.4. Older versions didn't attempt to flatten sub-selects in ways that would trigger this problem.
* Adjust mbutils.c so it won't get broken by future pgindent runs.Tom Lane2010-07-07
| | | | | | To do that, replace L'\0' by (WCHAR) 0. Perhaps someday we should teach pgindent about wide-character literals, but so long as this is the only use-case in the entire Postgres sources, a workaround seems easier.
* Make log_temp_files based on kB, and revert docs & comments to match.Robert Haas2010-07-06
| | | | | | | Per extensive discussion on pgsql-hackers. We are deliberately not back-patching this even though the behavior of 8.3 and 8.4 is unquestionably broken, for fear of breaking existing users of this parameter. This incompatibility should be release-noted.
* Support setting the keepalive idle time on MacOS X.Robert Haas2010-07-06
| | | | | | MacOS X uses TCP_KEEPALIVE rather than TCP_KEEPIDLE for this purpose. Thanks to Fujii Masao for the review.

* Split the LDFLAGS make variable into two parts: LDFLAGS is now used forTom Lane2010-07-05
| | | | | | | | | | | | | linking both executables and shared libraries, and we add on LDFLAGS_EX when linking executables or LDFLAGS_SL when linking shared libraries. This provides a significantly cleaner way of dealing with link-time switches than the former behavior. Also, make sure that the various platform-specific %.so: %.o rules incorporate LDFLAGS and LDFLAGS_SL; most of them missed that before. (I did not add these variables for the platforms that invoke $(LD) directly, however. It's not clear if we can do that safely, since for the most part we assume these variables use CC command-line syntax.) Per gripe from Aaron Swenson and subsequent investigation.
* The previous fix in CVS HEAD and 8.4 for handling the case where a cursorHeikki Linnakangas2010-07-05
| | | | | | | | | | | being used in a PL/pgSQL FOR loop is closed was inadequate, as Tom Lane pointed out. The bug affects FOR statement variants too, because you can close an implicitly created cursor too by guessing the "<unnamed portal X>" name created for it. To fix that, "pin" the portal to prevent it from being dropped while it's being used in a PL/pgSQL FOR loop. Backpatch all the way to 7.4 which is the oldest supported version.
* Don't set recoveryLastXTime when replaying a checkpoint --- that was a bogusTom Lane2010-07-03
| | | | | | | | idea from the start since the variable is only meant to track commit/abort events. This patch reverts the logic around the variable to what it was in 8.4, except that the value is now kept in shared memory rather than a static variable, so that it can be reported correctly by CreateRestartPoint (which is executed in the bgwriter).
* Make vacuum_defer_cleanup_age be PGC_SIGHUP level, since it's not sensibleTom Lane2010-07-03
| | | | | | | to have different values in different processes of the primary server. Also put it into the "Streaming Replication" GUC category; it doesn't belong in "Standby Servers" because you use it on the master not the standby. In passing also correct guc.c's idea of wal_keep_segments' category.
* Replace max_standby_delay with two parameters, max_standby_archive_delay andTom Lane2010-07-03
| | | | | | | | | | | | | | max_standby_streaming_delay, and revise the implementation to avoid assuming that timestamps found in WAL records can meaningfully be compared to clock time on the standby server. Instead, the delay limits are compared to the elapsed time since we last obtained a new WAL segment from archive or since we were last "caught up" to WAL data arriving via streaming replication. This avoids problems with clock skew between primary and standby, as well as other corner cases that the original coding would misbehave in, such as the primary server having significant idle time between transactions. Per my complaint some time ago and considerable ensuing discussion. Do some desultory editing on the hot standby documentation, too.
* Allow REASSIGNED OWNED to handle opclasses and opfamilies.Robert Haas2010-07-03
| | | | | | | | Backpatch to 8.3, which is as far back as we have opfamilies. The opclass portion could probably be backpatched to 8.2, when REASSIGN OWNED was added, but for now I have not done that. Asko Tiidumaa, with minor adjustments by me.
* Move copydir.c from src/port to src/backend/storage/fileRobert Haas2010-07-02
| | | | | | | | | | | | | The previous commit to make copydir() interruptible prevented postgres.exe from linking on MinGW and Cygwin, because on those platforms libpgport_srv.a can't freely reference symbols defined by the backend. Since that code is already backend-specific anyway, just move the whole file into the backend rather than adding further kludges to deal with the symbols needed by CHECK_FOR_INTERRUPTS(). This probably needs some further cleanup, but this commit just moves the file as-is, which should hopefully be enough to turn the buildfarm green again.
* Issue 'mkdir' hint when replying CREATE TABLESPACE in recovery mode.Bruce Momjian2010-07-02

* Allow ALTER TABLE .. SET TABLESPACE to be interrupted.Robert Haas2010-07-01

* stringToNode() and deparse_expression_pretty() crash on invalid input,Heikki Linnakangas2010-06-30
| | | | | | | | | | but we have nevertheless exposed them to users via pg_get_expr(). It would be too much maintenance effort to rigorously check the input, so put a hack in place instead to restrict pg_get_expr() so that the argument must come from one of the system catalog columns known to contain valid expressions. Per report from Rushabh Lathia. Backpatch to 7.4 which is the oldest supported version at the moment.

* Deprecate the use of => as an operator name.Robert Haas2010-06-22
| | | | | | | | | | In HEAD, emit a warning when an operator named => is defined. In both HEAD and the backbranches (except in 8.2, where contrib modules do not have documentation), document that hstore's text => text operator may be removed in a future release, and encourage the use of the hstore(text, text) function instead. This function only exists in HEAD (previously, it was called tconvert), so backpatch it back to 8.2, when hstore was added. Per discussion.
