* Update documentation for backslashes to mention escape string syntaxBruce Momjian2007-01-30
| | | | | | | | | | more, and standard_conforming_strings less, because in the future non-E strings will not treat backslashes specially. Also use E'' strings where backslashes are used in examples. (The existing examples would have drawn warnings.) Backpatch to 8.2.X.
* Repair oversights in the mechanism used to store compiled plpgsql functions.Tom Lane2007-01-30
| | | | | | | | | | | | | The original coding failed (tried to access deallocated memory) if there were two active call sites (fn_extra pointers) for the same function and the function definition was updated. Also, if an update of a recursive function was detected upon nested entry to the function, the existing compiled version was summarily deallocated, resulting in crash upon return to the outer instance. Problem observed while studying a bug report from Sergiy Vyshnevetskiy. Bug does not exist before 8.1 since older versions just leaked the memory of obsoleted compiled functions, rather than trying to reclaim it.
* Add SPI_push/SPI_pop calls so that datatype input and output functions calledTom Lane2007-01-30
| | | | | | | | | by plpgsql can themselves use SPI --- possibly indirectly, as in the case of domain_in() invoking plpgsql functions in a domain check constraint. Per bug #2945 from Sergiy Vyshnevetskiy. Somewhat arbitrarily, I've chosen to back-patch this as far as 8.0. Given the lack of prior complaints, it doesn't seem critical for 7.x.

* Add support for cross-type hashing in hash index searches and hash joins.Tom Lane2007-01-30
| | | | | | Hashing for aggregation purposes still needs work, so it's not time to mark any cross-type operators as hashable for general use, but these cases work if the operators are so marked by hand in the system catalogs.

* Improve hash join to discard input tuples immediately if they can'tTom Lane2007-01-28
| | | | | | match because they contain a null join key (and the join operator is known strict). Improves performance significantly when the inner relation contains a lot of nulls, as per bug #2930.
* Remove unnecessary checkpoint from PL regression tests. This was onceTom Lane2007-01-28
| | | | | | handy to prevent core dump files from disappearing, but it's useless now because (a) we don't drop core in individual DB subdirectories anymore, and (b) CREATE DATABASE forces an internal checkpoint anyway.
* Rename the uuid_t type to pg_uuid_t, to avoid a conflict with anyNeil Conway2007-01-28

* Repair oversight in creation of "append relations": we should set upTom Lane2007-01-28
| | | | | rel->tuples as well as rel->rows, since some estimation functions expect both to be valid in every baserel. Per report from Dave Dutcher.
* Make some small improvements in the accuracy of plpgsql's error locationTom Lane2007-01-28
| | | | | | reports; inspired by the misleading CONTEXT lines shown in recent bug report from Stefan Kaltenbrunner. Also, allow statement-type names shown in these messages to be translated.
* Fix path problem in MSVC bison wrapper. per Joachim Wieland.Andrew Dunstan2007-01-28

* Add a new builtin type, "uuid". This implements a UUID type, similar toNeil Conway2007-01-28
| | | | | | | | that defined in RFC 4122. This patch includes the basic implementation, plus regression tests. Documentation and perhaps some additional functionality will come later. Catversion bumped. Patch from Gevik Babakhani; review from Peter, Tom, and myself.
* Fix up plpgsql's "simple expression" evaluation mechanism so that it behavesTom Lane2007-01-28
| | | | | | | | | | | | | | safely in the presence of subtransactions. To ensure that any ExprContext shutdown callbacks are called at the right times, we have to have a separate EState for each level of subtransaction. Per "TupleDesc reference leak" bug report from Stefan Kaltenbrunner. Although I'm convinced the code is wrong as far back as 8.0, it doesn't seem that there are any ways for the problem to really manifest before 8.2: AFAICS, 8.0 and 8.1 only use the ExprContextCallback mechanism to handle set-returning functions, which cannot usefully be executed in a "simple expression" anyway. Hence, no backpatch before 8.2 --- the risk of unforeseen breakage seems to outweigh the chance of fixing something.

* Use autoconf build-in sys_siglist macro AC_DECL_SYS_SIGLIST, rather thanBruce Momjian2007-01-28

* Add a delay at the start of the stats test, to let any prior statsTom Lane2007-01-28
| | | | | | activity quiesce. Possibly this will fix the large increase in non-reproducible stats test failures we've noted since turning on stats_row_level by default.
* Dept of second thoughts: the IQ of estimate_array_length() needs to beTom Lane2007-01-28
| | | | | kept on par with that of scalararraysel(), else estimates that should track might not. Hence teach it about binary-compatible cases, too.
* Add signal.h for sys_siglist reference.Bruce Momjian2007-01-28
|
* Fix scalararraysel() to cope with binary-compatible cases, such as text[]Tom Lane2007-01-28
| | | | | | versus varchar[]. This oversight probably explains Ryan Holmes' recent complaint --- he was getting a generic selectivity estimate instead of anything intelligent.
* Use sys_siglist[] to print out signal names for signal exits, ratherBruce Momjian2007-01-28
| | | | than just numbers.
* Modify SGML makefile to allow 'gmake draft' to build draft html ('draft'Bruce Momjian2007-01-27
| | | | is now a target, no longer a modifier).
* Correct an old logic error in btree page splitting: when considering a splitTom Lane2007-01-27
| | | | | | | | | | | | exactly at the point where we need to insert a new item, the calculation used the wrong size for the "high key" of the new left page. This could lead to choosing an unworkable split, resulting in "PANIC: failed to add item to the left sibling" (or "right sibling") failure. Although this bug has been there a long time, it's very difficult to trigger a failure before 8.2, since there was generally a lot of free space on both sides of a chosen split. In 8.2, where the user-selected fill factor determines how much free space the code tries to leave, an unworkable split is much more likely. Report by Joe Conway, diagnosis and fix by Heikki Linnakangas.
