I am having a simmilar situation, but I am just starting to debug it.
Using 8.1.4
Have autovacuum running and it shows on the logs as running.
Ever couple of days in the last week when I tried to run vacuum analyze
postgresql complained that I needed to increase my fsm_pages.
I am going to start scheduling vacuum analyze in crontab.. but if autovacuum
is running shouldn't I not need to be running vacuum analyze?. and more
importantly shouldn't I not be running out of fsm_pages?
The first time I ran out.. I bumped it 100,000 over what it said it needed.
The manual vacuum analyze ran fine after that. The same has happened 3 times
so far.. 1 day apart (ie I have manually checked running vacuum analyze with
1 day difference) and I have increased it higher and higher. So if I was off
by 20K pages.. I increased to 100K.. then 200K over.. then 500K over..
Also, at what level does autovacuum shows more info? Going over the
archives.. I got the impression that it was debug2 so trying that. Does it
only show more info when it does work?
