Another question.
When autovacuum sleeps, does it release the lock it has on the table?
What we would like to have happen is for vacuum to work for a while, sleep, and while it is sleeping run an analyze on the table. We need this due to how quickly our data is changing. Currently we are running analyze every 5 minutes against the table of question and get a very serious performance hit when vacuum runs due to the index stats getting out of date. As soon as we rerun analyze after the vacuum happiness returns.
The pg_total_relation_size for the table in question is 64GB, and as stated above is a very heavily used and modifed table.
Thanks for any comments,
Chris
