* When using MSVC, disable the building of ecpg if pthreads is notBruce Momjian2007-01-24

* Get pg_utf_mblen(), pg_utf2wchar_with_len(), and utf2ucs() all on the sameTom Lane2007-01-24
| | | | | | | | | | | | | | | | | | | | | page about the maximum UTF8 sequence length we support (4 bytes since 8.1, 3 before that). pg_utf2wchar_with_len never got updated to support 4-byte characters at all, and in any case had a buffer-overrun risk in that it could produce multiple pg_wchars from what mblen claims to be just one UTF8 character. The only reason we don't have a major security hole is that most callers allocate worst-case output buffers; the sole exception in released versions appears to be pre-8.2 iwchareq() (ie, ILIKE), which can be crashed due to zeroing out its return address --- but AFAICS that can't be exploited for anything more than a crash, due to inability to control what gets written there. Per report from James Russell and Michael Fuhr. Pre-8.1 the risk is much less, but I still think pg_utf2wchar_with_len's behavior given an incomplete final character risks buffer overrun, so back-patch that logic change anyway. This patch also makes sure that UTF8 sequences exceeding the supported length (whichever it is) are consistently treated as error cases, rather than being treated like a valid shorter sequence in some places.
* Relax an Assert() that has been found to be too strict in some situationsTom Lane2007-01-24
| | | | | | | involving unions of types having typmods. Variants of the failure are known to occur in 8.1 and up; not sure if it's possible in 8.0 and 7.4, but since the code exists that far back, I'll just patch 'em all. Per report from Brian Hurt.
* Simplify handling of XML error messages: Just use the string provided byPeter Eisentraut2007-01-23
| | | | | | | | | libxml as the detail message. As per <http://archives.postgresql.org/pgsql-hackers/2006-12/msg01087.php>. For converting error codes to messages, we only need to cover those codes that we raise ourselves now.

* Back out use of FormatMessage(), does error values, not exceptionBruce Momjian2007-01-23

* Put back planner's ability to cache the results of mergejoinscansel(),Tom Lane2007-01-22
| | | | | | | | | | which I had removed in the first cut of the EquivalenceClass rewrite to simplify that patch a little. But it's still important --- in a four-way join problem mergejoinscansel() was eating about 40% of the planning time according to gprof. Also, improve the EquivalenceClass code to re-use join RestrictInfos rather than generating fresh ones for each join considered. This saves some memory space but more importantly improves the effectiveness of caching planning info in RestrictInfos.

* Adjust pgbench so it won't spit up on non-select queries returningTom Lane2007-01-22
| | | | | tuples, which is entirely possible with custom scripts (consider RETURNING, EXPLAIN, etc).
* Add COST and ROWS options to CREATE/ALTER FUNCTION, plus underlying pg_procTom Lane2007-01-22
| | | | | | | | | | | | columns procost and prorows, to allow simple user adjustment of the estimated cost of a function call, as well as control of the estimated number of rows returned by a set-returning function. We might eventually wish to extend this to allow function-specific estimation routines, but there seems to be consensus that we should try a simple constant estimate first. In particular this provides a relatively simple way to control the order in which different WHERE clauses are applied in a plan node, which is a Good Thing in view of the fact that the recent EquivalenceClass planner rewrite made that much less predictable than before.

* Simplify pg_am representation of ordering-capable access methods:Tom Lane2007-01-20
| | | | | | | provide just a boolean 'amcanorder', instead of fields that specify the sort operator strategy numbers. We have decided to require ordering-capable AMs to use btree-compatible strategy numbers, so the old fields are overkill (and indeed misleading about what's allowed).

* List disabled triggers separately in psql's "\d <table>" output.Neil Conway2007-01-20
| | | | | Previously, disabled triggers were not displayed any differently than enabled ones, which was quite misleading. Patch from Brendan Jurd.
* Refactor planner's pathkeys data structure to create a separate, explicitTom Lane2007-01-20
| | | | | | | | | | | | | | representation of equivalence classes of variables. This is an extensive rewrite, but it brings a number of benefits: * planner no longer fails in the presence of "incomplete" operator families that don't offer operators for every possible combination of datatypes. * avoid generating and then discarding redundant equality clauses. * remove bogus assumption that derived equalities always use operators named "=". * mergejoins can work with a variety of sort orders (e.g., descending) now, instead of tying each mergejoinable operator to exactly one sort order. * better recognition of redundant sort columns. * can make use of equalities appearing underneath an outer join.
* Refactor the index AM API slightly: move currentItemData andNeil Conway2007-01-20

* The libpq library directory was mentioned here in the wrong place, whichPeter Eisentraut2007-01-20
| | | | | might lead to a previously installed libpq being used instead. But we don't actually have to link with libpq here at all, so remove it.
