Disabling autovacuum can have catastrophic effects, since it disables the ANALYZing of tables.
Can we have a mode where we disable autoVACUUM yet enable autoANALYZE? ANALYZE times are fairly bounded because of the way we do sampling. VACUUM times are not bounded at all, and typically > O(n). So it makes sense to switch off the VACUUM at certain times, but never good to switch off ANALYZE. While we're there, it would be useful if CREATE TABLE AS SELECT was followed by an automatic ANALYZE. Especially important for temp tables. -- Simon Riggs www.2ndQuadrant.com PostgreSQL Training, Services and Support -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
