* Specify lo_write() to take a _const_ buffer, to match documentation.Bruce Momjian2006-09-07
|
* Change processing of extended-Query mode so that an unnamed statementTom Lane2006-09-06
| | | | | | | | that has parameters is always planned afresh for each Bind command, treating the parameter values as constants in the planner. This removes the performance penalty formerly often paid for using out-of-line parameters --- with this definition, the planner can do constant folding, LIKE optimization, etc. After a suggestion by Andrew@supernews.
* Get rid of the separate RULE privilege for tables: now only a table's ownerTom Lane2006-09-05
| | | | | | | | | | | | | can create or modify rules for the table. Do setRuleCheckAsUser() while loading rules into the relcache, rather than when defining a rule. This ensures that permission checks for tables referenced in a rule are done with respect to the current owner of the rule's table, whereas formerly ALTER TABLE OWNER would fail to update the permission checking for associated rules. Removal of separate RULE privilege is needed to prevent various scenarios in which a grantee of RULE privilege could effectively have any privilege of the table owner. For backwards compatibility, GRANT/REVOKE RULE is still accepted, but it doesn't do anything. Per discussion here: http://archives.postgresql.org/pgsql-hackers/2006-04/msg01138.php
* Make Gen_fmgrtab.sh locale-proof. Per report from Marko Kreen andTom Lane2006-09-05
| | | | fix suggestion from Peter.
* Fix Intel compiler bug. Per discussionTeodor Sigaev2006-09-05

* Fix information_schema.key_column_usage to show correct value ofTom Lane2006-09-04
| | | | | position_in_unique_constraint (column newly added per SQL2003). Greg Mullane
* Trivial patch to double vacuum speed on tables with no indexes (preventBruce Momjian2006-09-04
| | | | | | second scan of table). Gregory Stark
* Disallow TRUNCATE when there are any pending after-trigger events forTom Lane2006-09-04
| | | | | | | the target relation(s). There might be some cases where we could discard the pending event instead, but for the moment a conservative approach seems sufficient. Per report from Markus Schiltknecht and subsequent discussion.
* Sequences were not being shown due to the use of lowercase 's' insteadBruce Momjian2006-09-04
| | | | | | | of 'S', and the views were not checking for table visibility with regards to temporary tables and sequences. Greg Sabino Mullane
* Change ILIKE to invoke lower() and then do plain LIKE comparison whenTom Lane2006-09-04
| | | | | | | working in a multibyte encoding. This fixes the problems exhibited in bug #1931 and other reports of ILIKE misbehavior in UTF8 encoding. It's a pretty grotty solution though --- should rethink how to do it after we install better locale support, someday.
* Add missing gettext calls for some SSL errors.Peter Eisentraut2006-09-04
|
* Fix interval input parser so that fractional weeks and months areTom Lane2006-09-04
| | | | | | | cascaded first to days and only what is leftover into seconds. This seems to satisfy the principle of least surprise given the general conversion to three-part interval values --- it was an oversight that these cases weren't dealt with in 8.1. Michael Glaesemann
* Code review for UPDATE SET (columnlist) patch. Make it handle as muchTom Lane2006-09-03
| | | | | | of the syntax as this fundamentally dead-end approach can, in particular combinations of single and multi column assignments. Improve rather inadequate documentation and provide some regression tests.
* Arrange for GetSnapshotData to copy live-subtransaction XIDs from theTom Lane2006-09-03
| | | | | | | | | | PGPROC array into snapshots, and use this information to avoid visits to pg_subtrans in HeapTupleSatisfiesSnapshot. This appears to solve the pg_subtrans-related context swap storm problem that's been reported by several people for 8.1. While at it, modify GetSnapshotData to not take an exclusive lock on ProcArrayLock, as closer analysis shows that shared lock is always sufficient. Itagaki Takahiro and Tom Lane
* Properly round months into days and into seconds for intervalBruce Momjian2006-09-03
| | | | | | | multiplication/division queries like select '41 mon 10:00:00'::interval / 10 as "pos". Report from Michael Glaesemann
* Revert FETCH/MOVE int64 patch. Was using incorrect checks forBruce Momjian2006-09-03
| | | | fetch/move in scan.l.
* Fix case where "PM" to_timestamp() mask was eating too many characters.Bruce Momjian2006-09-03
| | | | Report from Josh Tolley.
* Fix LLONG_MAX define used by new int64 FETCH/MOVE patch.Bruce Momjian2006-09-03
|
* Remove unnecessary copyObject() call in update (values) code.Bruce Momjian2006-09-03
|
* Make autovacuum behavior more agressive, per discussion on hackers listBruce Momjian2006-09-02
| | | | | | | --- was part of autovacuum default 'on' patch that was reverted, but we want this part. Peter Eisentraut
* Update postgresql.conf line for default superuser_reserved_connections.Bruce Momjian2006-09-02
|
* Change "superuser_reserved_connections" default to 3, because ofBruce Momjian2006-09-02
| | | | possible autovacuum use.
* Small code cleanup for recent UPDATE SET (values) patch.Bruce Momjian2006-09-02

* Remove GUC_REPORT for new "server_version_num" GUC variable. AddedBruce Momjian2006-09-02
| | | | overhead for every connection, per Tom.
* Apply a simple solution to the problem of making INSERT/UPDATE/DELETETom Lane2006-09-02
| | | | | | | | | | | | | | | RETURNING play nice with views/rules. To wit, have the rule rewriter rewrite any RETURNING clause found in a rule to produce what the rule's triggering query asked for in its RETURNING clause, in particular drop the RETURNING clause if no RETURNING in the triggering query. This leaves the responsibility for knowing how to produce the view's output columns on the rule author, without requiring any fundamental changes in rule semantics such as adding new rule event types would do. The initial implementation constrains things to ensure that there is exactly one, unconditionally invoked RETURNING clause among the rules for an event --- later we might be able to relax that, but for a post feature freeze fix it seems better to minimize how much invention we do. Per gripe from Jaime Casanova.
* Add new variable "server_version_num", which is almost the same asBruce Momjian2006-09-02
| | | | | | | | "server_version" but uses the handy PG_VERSION_NUM which allows apps to do things like if ($version >= 80200) without having to parse apart the value of server_version themselves. Greg Sabino Mullane greg@turnstep.com
* Clean up rather sloppy fix in HEAD for the ancient bug that CREATE CONVERSIONTom Lane2006-08-31
| | | | | didn't create a dependency from the new conversion to its schema. Back-patch to all supported releases.
* Repair interpretation of GB as MB.Peter Eisentraut2006-08-31

* Attibution addition: Add Karel Zak also for COPY SELECT.Bruce Momjian2006-08-31

* Update logging of prepare/execute syntax, per comments from Guillaume Smet.Bruce Momjian2006-08-30

* Separate prepared statement and bind parameters with comma.Bruce Momjian2006-08-29

* Revert change to turn autovacuum on by default.Peter Eisentraut2006-08-29

* Only call log_after_parse() if necessary.Bruce Momjian2006-08-29
|
* Now bind displays prepare as detail, and execute displays prepare andBruce Momjian2006-08-29
| | | | | | | | | | optionally bind. I re-added the "statement:" label so people will understand why the line is being printed (it is log_*statement behavior). Use single quotes for bind values, instead of double quotes, and double literal single quotes in bind values (and document that). I also made use of the DETAIL line to have much cleaner output.
* Fix pgstat_report_waiting() to not dump core if called beforeTom Lane2006-08-28
| | | | | | | | | | pgstat_bestart() has been called; else any lock-block occurring during InitPostgres() is disastrous. I believe this explains recent wasp regression failure; at least it explains the crash I got while trying to duplicate the problem. I also made pgstat_report_activity() safe against the same scenario, just in case. The report_waiting hazard was created by my patch of 19-Aug to include waiting status in pg_stat_activity.
* Tweak trivial_subqueryscan() to consider a SubqueryScan's targetlistTom Lane2006-08-28
| | | | | | | trivial if it contains either Vars referencing the corresponding subplan columns, or Consts equaling the corresponding subplan columns. This lets the planner eliminate the SubqueryScan in some cases generated by generate_setop_tlist().
* Turn autovacuum on by default. (stats_row_level is also on by default.)Peter Eisentraut2006-08-28
| | | | Threshold and scale factor are cut in half for more aggressive behavior.
* Add new return codes SPI_OK_INSERT_RETURNING etc to the SPI API.Tom Lane2006-08-27
| | | | | | | Fix all the standard PLs to be able to return tuples from FOO_RETURNING statements as well as utility statements that return tuples. Also, fix oversight that SPI_processed wasn't set for a utility statement returning tuples. Per recent discussion.
* Add some notes about why it's not a bug that RI_FKey_check callsTom Lane2006-08-27
| | | | | HeapTupleSatisfiesItself without doing LockBuffer first. This code is a bit fragile, but AFAICS it's not actually broken.
* Add a function GetLockConflicts() to lock.c to report xacts holdingTom Lane2006-08-27
| | | | | | | | | locks that would conflict with a specified lock request, without actually trying to get that lock. Use this instead of the former ad hoc method of doing the first wait step in CREATE INDEX CONCURRENTLY. Fixes problem with undetected deadlock and in many cases will allow the index creation to proceed sooner than it otherwise could've. Per discussion with Greg Stark.
* Move xact.c's partial support for Lists of TransactionIds into pg_list.h.Tom Lane2006-08-27
| | | | Needed because lock.c is now going to use the same type of list.
* Add the ability to create indexes 'concurrently', that is, withoutTom Lane2006-08-25
| | | | | blocking concurrent writes to the table. Greg Stark, with a little help from Tom Lane.
* Add some debug logging code to AllocateFile's failure path to log theTom Lane2006-08-24
| | | | | specific Windows error code (GetLastError). This is a hopefully temporary hack to try to diagnose rare failures. Magnus Hagander
