* Do a CHECK_FOR_INTERRUPTS after emitting a message of less than ERRORTom Lane2006-10-01
| | | | | | | severity. This is to ensure the user can cancel a query that's spitting out lots of notice/warning messages, even if they're coming from a loop that doesn't otherwise contain a CHECK_FOR_INTERRUPTS. Per gripe from Stephen Frost.
* Fix overly enthusiastic Assert introduced in 8.1: it's expecting aTom Lane2006-10-01
| | | | | CaseTestExpr, but forgot that the optimizer is sometimes able to replace CaseTestExpr by Const.
* BSD/OS doesn't have a prototype for strlcpy() but has the function, soBruce Momjian2006-09-30
| | | | work around that with defines.
* Allow assignment to array elements not contiguous with those alreadyTom Lane2006-09-29
| | | | | | | | | | present; intervening positions are filled with nulls. This behavior is required by SQL99 but was not implementable before 8.2 due to lack of support for nulls in arrays. I have only made it work for the one-dimensional case, which is all that SQL99 requires. It seems quite complex to get it right in higher dimensions, and since we never allowed extension at all in higher dimensions, I think that must count as a future feature addition not a bug fix.
* Fix IS NULL and IS NOT NULL tests on row-valued expressions to conform toTom Lane2006-09-28
| | | | | | | | | | | | the SQL spec, viz IS NULL is true if all the row's fields are null, IS NOT NULL is true if all the row's fields are not null. The former coding got this right for a limited number of cases with IS NULL (ie, those where it could disassemble a ROW constructor at parse time), but was entirely wrong for IS NOT NULL. Per report from Teodor. I desisted from changing the behavior for arrays, since on closer inspection it's not clear that there's any support for that in the SQL spec. This probably needs more consideration.
* Fix a couple other places that need to know about (some) src/port/ filesTom Lane2006-09-28
| | | | explicitly.
* Oops, forgot that libpq needs extra steps to make use of src/port/ files.Tom Lane2006-09-27
|
* Replace strncpy with strlcpy in selected places that seem possibly relevantTom Lane2006-09-27
| | | | | | | to performance. (A wholesale effort to get rid of strncpy should be undertaken sometime, but not during beta.) This commit also fixes dynahash.c to correctly truncate overlength string keys for hashtables, so that its callers don't have to anymore.
* Add strlcpy() to the set of functions supported by src/port/ when notTom Lane2006-09-27
| | | | | available directly on the platform. Per discussion, this function is sufficiently widely recognized to be treated as standard.
* Fix some misuses of strncat().Tom Lane2006-09-27

* Remove separate strdup.h header file; it's redundant with port.h.Tom Lane2006-09-27

* Degrade the transaction-id wraparound point message from LOG to DEBUG1, perAlvaro Herrera2006-09-26

* Added Joachim's changes for MinGW.Michael Meskes2006-09-26
| | | | Added SET DATESTYLE to one test so the output format is defined.
* Increase default value of effective_cache_size to 128MB, per discussion.Tom Lane2006-09-25

* Add a check to prevent overwriting valid data if smgrnblocks() gives aTom Lane2006-09-25
| | | | | | wrong answer, as has been seen to occur with a buggy Linux kernel. Not really our bug, but it's a simple test in a seldom-used control path, so might as well have a defense.
* Fix notice message from DROP FUNCTION IF EXISTS, and improve messageTom Lane2006-09-25
| | | | for DROP AGGREGATE IF EXISTS. Per report from Teodor.
* Fix incorrect mapping of fopen mode 'a' in recently-added code toTom Lane2006-09-24
| | | | make fopen work safely on Windows. Magnus
* Cause pg_regress to invoke the temporary postmaster as 'postgres' notTom Lane2006-09-24
| | | | | | 'postmaster', so as not to depend on the existence of the postmaster symlink. Also, implement postmaster-still-alive and postmaster-kill operations for Windows, per Magnus.
* Suppress useless warning on pre-XP versions of Windows. MagnusTom Lane2006-09-24

* Tag us Beta1REL8_2_BETA1PostgreSQL Daemon2006-09-23

* Fix pg_locks view to call advisory locks advisory locks, while preservingTom Lane2006-09-22
| | | | | backward compatibility for anyone using the old userlock code that's now on pgfoundry --- locks from that code still show as 'userlock'.
* Fix bugs in plpgsql and ecpg caused by assuming that isspace() would onlyTom Lane2006-09-22
| | | | | | | | | return true for exactly the characters treated as whitespace by their flex scanners. Per report from Victor Snezhko and subsequent investigation. Also fix a passel of unsafe usages of <ctype.h> functions, that is, ye olde char-vs-unsigned-char issue. I won't miss <ctype.h> when we are finally able to stop using it.
* Surely this temp buffer needn't be static.Tom Lane2006-09-22

* Rearrange yes/no prompting code so that the prompts always show thePeter Eisentraut2006-09-22
| | | | | | | (possibly (un)translated) letters that are actually expected as input. Also reject invalid responses instead of silenty taken them as "no". with help from Bernd Helmle
* Add units to the default postgresql.conf. For the most part, this shouldPeter Eisentraut2006-09-22
| | | | | match what SHOW displays as default value, to make the user experience uniform.
* Fix free space map to correctly track the total amount of FSM space neededTom Lane2006-09-21
| | | | | | | even when a single relation requires more than max_fsm_pages pages. Also, make VACUUM emit a warning in this case, since it likely means that VACUUM FULL or other drastic corrective measure is needed. Per reports from Jeff Frost and others of unexpected changes in the claimed max_fsm_pages need.
* Change patternsel (LIKE/regex selectivity estimation) so that if thereTom Lane2006-09-20
| | | | | | | | | is a large enough histogram, it will use the number of matches in the histogram to derive a selectivity estimate, rather than the admittedly pretty bogus heuristics involving examining the pattern contents. I set 'large enough' at 100, but perhaps we should change that later. Also apply the same technique in contrib/ltree's <@ and @> estimator. Per discussion with Stefan Kaltenbrunner and Matteo Beccati.
* Improve usage of effective_cache_size parameter by assuming that all theTom Lane2006-09-19
| | | | | | | | | | | tables in the query compete for cache space, not just the one we are currently costing an indexscan for. This seems more realistic, and it definitely will help in examples recently exhibited by Stefan Kaltenbrunner. To get the total size of all the tables involved, we must tweak the handling of 'append relations' a bit --- formerly we looked up information about the child tables on-the-fly during set_append_rel_pathlist, but it needs to be done before we start doing any cost estimation, so push it into the add_base_rels_to_query scan.
* Fix shared library creation to work properly on AIX. Albe LaurenzTom Lane2006-09-19

* Add built-in userlock manipulation functions to replace the formerTom Lane2006-09-18
| | | | | | | contrib functionality. Along the way, remove the USER_LOCKS configuration symbol, since it no longer makes any sense to try to compile that out. No user documentation yet ... mmoncure has promised to write some. Thanks to Abhijit Menon-Sen for creating a first draft to work from.
* Fix problems with column name list of CREATE TABLE AS being applied toTom Lane2006-09-18
| | | | | the input query's target list too soon, causing it to affect processing of ORDER BY in the input query.
* Fix CREATE TABLE ... AS VALUES ... to work rather than Assert'ing;Tom Lane2006-09-18
| | | | | | oversight in original implementation of VALUES. Also fix an oversight in recent addition of options to CREATE TABLE AS: they weren't getting propagated if the query was a set-operation such as UNION.
* Change ANALYZE to take ShareUpdateExclusiveLock not AccessShareLock onTom Lane2006-09-17
| | | | | | | | | | | | the table being analyzed. This prevents two ANALYZEs from running concurrently on the same table and possibly suffering concurrent-update failures while trying to store their results into pg_statistic. The downside is that a database-wide ANALYZE executed within a transaction block will hold ShareUpdateExclusiveLock on many tables simultaneously, which could lead to concurrency issues or even deadlock against another such ANALYZE. However, this seems a corner case of less importance than getting unexpected errors from a foreground ANALYZE when autovacuum elects to analyze the same table concurrently. Per discussion.
* Marginal cleanup in arrangements for ensuring StrategyHintVacuum is clearedTom Lane2006-09-17
| | | | | | | | | after an error during VACUUM. We have a PG_TRY block anyway around the only call sites, so just reset it in the CATCH clause instead of having AtEOXact_Buffers blindly do it during xact end. I think the old code was actively wrong for the case of a failure during ANALYZE inside a subtransaction --- the flag wouldn't get cleared until main transaction end. Probably not worth back-patching though.
* Rename the recently-added pg_timezonenames view to pg_timezone_abbrevs,Tom Lane2006-09-16
| | | | | | and create a new view pg_timezone_names that provides information about the zones known in the 'zic' database. Magnus Hagander, with some additional work by Tom Lane.
* Update timezone data files to release 2006k of the zic database.Tom Lane2006-09-16

* Fix some uses of str[n]casecmp that should be pg_str[n]casecmp,Tom Lane2006-09-15

* Make postgresql.conf.sample match the initdb defaults. This fixesBruce Momjian2006-09-14
| | | | comment alignment on most systems.
* Add a couple of information functions to support direct checks on whetherTom Lane2006-09-14
| | | | | | a schema is our own temp schema or another backend's temp schema, and use these in place of some former kluges in information_schema. Per my proposal of yesterday.
* Improve error message. Per discussionTeodor Sigaev2006-09-14
| | | | http://archives.postgresql.org/pgsql-general/2006-09/msg00186.php
* Cygwin systems seem to have a different error message when trying to connect ↵Michael Meskes2006-09-14
| | | | to port 0. Let's try port 20 instead.
* Added missing constuctor/destructor for interval and date.Michael Meskes2006-09-14

* Make logging of extended-protocol commands a bit more consistent, perTom Lane2006-09-13
