PostgreSQL 8.4/FreeBSD 7.2 amd64
I have a database which has 3 tables which get a very high level of activity (about 40 thousand updates per minute).
The tables are getting quite bloated, since autovacuum is apparently not optimally configured (it is using the default settings).
Anything I do must be such that it will not cause deadlocks, since the effects can be catastrophic with the amount of data being pumped through the system.
Initially, I had scheduled tasks through pgagent running a vacuum analyze every 15 minutes, but other posts I have read here have stated this could cause deadlocks, and mentioned running autovacuum is preferable
.
Also, are rows “vacuumed” in the indices made available without having to reindex? The reason I am asking is because the indices seem to be bloating to a much higher factor than the data table.
Thanks in advance
