* Disable query cancel during HandleDeadLock().Hiroshi Inoue2001-01-09

* 1. Checkpoint.undo may be after checkpoint itself:Vadim B. Mikheev2001-01-09
| | | | | | | | - no more elog(STOP) in StartupXLOG(); - both checkpoint' undo & redo are used to define oldest on-line log file. 2. Ability to pre-allocate a few log files at checkpoint time (wal_files option). Off by default.
* Fix oversight in planning of GROUP queries: when an expression is usedTom Lane2001-01-09
| | | | | | | | as both a GROUP BY item and an output expression, the top-level Group node should just copy up the evaluated expression value from its input, rather than re-evaluating the expression. Aside from any performance benefit this might offer, this avoids a crash when there is a sub-SELECT in said expression.
* Fix small but critical typo ...Tom Lane2001-01-09

* Prevent vacuumdb from trying to vacuum template0.Tom Lane2001-01-08
|
* Remove compiler warning about uninitialized warnings.Bruce Momjian2001-01-08
|
* check for failure after vacuuming each DB, not only the last one.Tom Lane2001-01-08
|
* Add some debugging support code (ifdef'd out in normal use).Tom Lane2001-01-08
|
* LockBuffer should not elog while holding buffer's cntx_lock.Tom Lane2001-01-08
|
* Keep relations open until they are no longer needed.Hiroshi Inoue2001-01-08
|
* Make outfuncs/readfuncs treat OIDs properly as unsigned values. Clean upTom Lane2001-01-08
| | | | | inconsistent coding practices for handling Index values and booleans, too.
* Correct nasty error in heap_update: it was releasing the buffer refcountTom Lane2001-01-07
| | | | | | | | | before calling RelationInvalidateHeapTuple(), which is bad because the latter needs to look at the tuple data, which is in the shared disk buffer. If another backend manages to recycle the buffer while this is going on, we will compute the wrong hashindex for the tuple or maybe even crash outright. Must hold buffer refcount until afterwards. (This bug is not in 7.0.*; seems to be have introduced during WAL changes.)
* Clear QueryCancel and ProcDiePending at start of proc_exit, to ensureTom Lane2001-01-07
| | | | that leftover cancel/die requests cannot interfere with exit activities.
* Fix recent breakage of query-cancel logic, see my pghackers messageTom Lane2001-01-07
| | | | of 6 Jan 2001 21:55.
* Resultmap updates for OpenBSD, per report from bpalmer@crimelabs.net.Tom Lane2001-01-07
|
* Modify readfuncs so that recursive use of stringToNode will not crashTom Lane2001-01-07
| | | | | | | | and burn. Just for added luck, change reading of CONST nodes so that we do not need to consult pg_type rows while reading them; this means that no database access occurs during stringToNode. This requires changing the order in which const-node fields are written, which means an initdb is forced.
* Clean up checking of relkind for ALTER TABLE and LOCK TABLE commands.Tom Lane2001-01-07
| | | | | Disallow cases like adding constraints to sequences :-(, and eliminate now-unnecessary search of pg_rewrite to decide if a relation is a view.
* Log memory context stats to stderr when reporting a 'Memory exhausted'Tom Lane2001-01-06
| | | | error, so as to provide a starting point for debugging.
* Fix memory leak in relcache handling of rules: allocate rule parsetreesTom Lane2001-01-06
| | | | | | in per-entry sub-memory-context, where they were supposed to go, rather than in CacheMemoryContext where the code was putting them. Must've suffered a severe brain fade when I wrote this :-(
* Polish help output. Allow --help to work with BSD getopts.Peter Eisentraut2001-01-06
|
* No need for screen_size to be static.Tom Lane2001-01-06
|
* Simplify the rules that explicitly allowed TYPE as a type name (which isPeter Eisentraut2001-01-06
| | | | | no longer the case). Add AND and TRAILING to ColLabel. All key words except AS are now at least ColLabel's.
* Fix copy to make it more robust against unexpected characterTatsuo Ishii2001-01-06
| | | | | | | | sequences. This is done by disabling multi-byte awareness when it's not necessary. This is kind of a workaround, not a perfect solution. However, there is no ideal way to parse broken multi-byte character sequences. So I guess this is the best way what we could do right now...
* init_irels() is changed to be called in RelationCacheInitializePhase2()Hiroshi Inoue2001-01-06
| | | | so that transactional control could guarantee the consistency.
* Fix NOT NULL option for plpgsql variables (doesn't look like itTom Lane2001-01-06
| | | | could ever have worked...)
* Fix misplaced strdup(), which could lead to error messages referencingTom Lane2001-01-06
| | | | deallocated memory later on.
* Rename and document some invalidation routines to make it clearer thatTom Lane2001-01-05
| | | | | they don't themselves flush any cache entries, only add to to-do lists that will be processed later.
* Remove not-really-standard implementation of CREATE TABLE's UNDER clause,Tom Lane2001-01-05
| | | | | | | | | | | and revert documentation to describe the existing INHERITS clause instead, per recent discussion in pghackers. Also fix implementation of SQL_inheritance SET variable: it is not cool to look at this var during the initial parsing phase, only during parse_analyze(). See recent bug report concerning misinterpretation of date constants just after a SET TIMEZONE command. gram.y really has to be an invariant transformation of the query string to a raw parsetree; anything that can vary with time must be done during parse analysis.
* Disallow creation of a child table by a user who does not own the parentTom Lane2001-01-05
| | | | table, per pghackers discussion around 22-Dec-00.
* Correct path where to check for password file existance.Peter Eisentraut2001-01-04
|
* Clean up some unnecessary fragility in EXECUTE command.Tom Lane2001-01-04
|
* Repair guaranteed core dump in SPI_exec(). Guess this routine wasn'tTom Lane2001-01-04
| | | | used before ...
* I neglected to remove a debug message,sorry.Hiroshi Inoue2001-01-04
|
* pg_dump failed to handle backslashes embedded in function definitionsTom Lane2001-01-04
| | | | | (and most other places where it needed to output a string literal, too, except for data INSERT statements). Per bug report from Easter, 12/1/00.
* Fix breakage of rules using NOTIFY actions, per bug report and patchTom Lane2001-01-03
| | | | from sergiop@sinectis.com.ar.
* New file format for COPY BINARY, in accordance with pghackers discussionsTom Lane2001-01-03
| | | | of early December 2000. COPY BINARY is now TOAST-safe.
* MakeRetrieveViewRuleName was scribbling on memory that didn't belongTom Lane2001-01-03
| | | | to it. Bad dog.
* Repair always-broken date_part('quarter',timestamp).Thomas G. Lockhart2001-01-03
| | | | | | | Previous result did not have correct month boundaries so anything near edge cases was suspect (e.g. April was in Q1 and July, August were lumped into Q2). Thanks to Denis Osadchy <osadchy@turbo.nsk.su> for the report.
* I've found a memory leak in libecpg of PostgreSQL 7.0.3.Bruce Momjian2001-01-02
| | | | | | | | | The leak is caused by the memory allocation in src/interfaces/ecpg/lib/execute.c in line 669 which is never freed. Adding a "free(array_query);" after PQexec in line 671 seems to fix the leak. Thorsten Knabe
* Document tuple ordering differences as a possible cause ofTom Lane2001-01-02
| | | | regression test 'failures'.
* Clean up non-reentrant interface for hash_seq/HashTableWalk, so thatTom Lane2001-01-02
| | | | | | | | starting a new hashtable search no longer clobbers any other search active anywhere in the system. Fix RelationCacheInvalidate() so that it will not crash or go into an infinite loop if invoked recursively, as for example by a second SI Reset message arriving while we are still processing a prior one.
* Tweak temporary-installation setup so that it doesn't break when theTom Lane2001-01-02
| | | | configured install --prefix begins with /data/...
* Update geometry-alpha-precision.out per reports from Brent Verner andTom Lane2001-01-01
| | | | Adriaan Joubert.
* CLUSTER forgot to create a TOAST table for the clustered relation.Tom Lane2001-01-01
|
* Ensure attcacheoff is written out as -1 when writing pg_attributeTom Lane2001-01-01
| | | | tuples for a relation. Needed to prevent Assert failure in CLUSTER.
* Update comment.Tom Lane2001-01-01
|
* Mark geometric 'overlaps' operators (&&) as self-commutative.Tom Lane2000-12-31
|
* Fix typo in error message.Tom Lane2000-12-31
|
* Don't say 'export PGHOST' or 'export PGPORT' unless we actually defineTom Lane2000-12-31
| | | | | those variables. Some shells will invent an empty-string definition in this case, which is not what we want.
* On further thought, we need a defense against empty PGPORT here too.Tom Lane2000-12-31
