Change patternsel (LIKE/regex selectivity estimation) so that if there
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

Improvements to the partitioning documentation. Original patch from Greg
Stark, additional fixes and editorialization by Neil Conway. Greg's patch
description:
Some more doc patches for partitioned tables. In particular replace
the caveat that INCLUDING CONSTRAINTS doesn't exist and replace it
with documentation of, well, INCLUDING CONSTRAINTS.
Also, there was an instance of "LIKE WITH DEFAULTS" which is
actually spelled "LIKE INCLUDING DEFAULTS".
Tom Lane [2006年9月19日 22:49:53 +0000 (22:49 +0000)]
Improve usage of effective_cache_size parameter by assuming that all the
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.
Do a round of copy-editing for the release notes: fix some typos and

< o -Have COPY return the number of rows loaded/unloaded?

< Currently, while \e saves a single statement as one entry, interactive
< statements are saved one line at a time. Ideally all statements
< would be saved like \e does.
<
< o -Allow multi-line column values to align in the proper columns

< * -Add system view to show free space map contents
< * -Allow installing to directories containing spaces
<
< This is possible if proper quoting is added to the makefiles for the
< install targets. Because PostgreSQL supports relocatable installs, it
< is already possible to install into a directory that doesn't contain
< spaces and then copy the install to a directory with spaces.

Change ANALYZE to take ShareUpdateExclusiveLock not AccessShareLock on
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.
Tom Lane [2006年9月17日 22:16:22 +0000 (22:16 +0000)]
Marginal cleanup in arrangements for ensuring StrategyHintVacuum is cleared
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.
