Re: Autovacuum / full vacuum

Well,

I think that the documentation is not exactly easy to understand. I 
always wondered why there are no examples for common postgresql 
configurations. All I know is that the default configuration seems to be 
too low for production use. And while running postgres I get no hints as 
to which setting needs to be increased to improve performance. I have no 
chance to see if my FSM settings are too low other than to run vacuum 
full verbose in psql, pipe the result to a text file and grep for some 
words to get a somewhat comprehensive idea of how much unused space 
there is in my system.

Don't get me wrong - I really like PostgreSQL and it works well in my 
application. But somehow I feel that it might run much better ...

about the FSM: You say that increasing the FSM is fairly cheap - how 
should I know that?
