* 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 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.
* Update TODO for short header versions:Bruce Momjian2006-09-16
| | | | | | | | | | | | | | | | | | | | | | | | < o Reorder physical storage order to reduce padding? < < This involves having the user-specified order of columns < be different from the physical order. SELECT * would < need to reorder the physical values to match the < user-specified ordering. < < o Store disk pages with no alignment/padding? < < This necessitates adding CPU-required padding when moving < rows from disk to memory. < < One idea is to store the header in network byte order (high bits < first), and read the high bits to determine the header length. < http://archives.postgresql.org/pgsql-hackers/2006-09/msg00848.php > One idea is to create zero-or-one-byte-header versions > of varlena data types.

* Rename xml_valid() to xml_is_well_formed(), but provide a temporaryTom Lane2006-09-16
