Re: [PERFORM] PostgreSQL with Zabbix - problem of newbe

[Grzegorz Jaśkiewicz]

starting with 8.3, there's this new feature called HOT, which helps a lot
when you do loads of updates.
Plus writer is much quicker (30-40% sometimes), and autovacuum behaves much
nicer.
Bottom line, upgrade to 8.3, 8.1 had autovacuum disabled by default for a
reason.
