Vacuum

From
Tim Stoddard
Date:
When I delete 2k-3k of records from a table the vacuum process seems
to take forever.  I have let the vacuum run for 24 hours before with
not luck.

Can someone one explain to me what is going on?

Funny, there is/was just a whole thread about that on hackers. There seem to
be some agreement that this will be reworked/faster in 6.6, but you cannot
avoid it currently. The main cause for this is the usage of indeces.

Did you pass -o -F to the postmaster? It can improve the speed of PostgreSQL
dramatically.

This vacuum speedup may be in 6.5, thanks to Vadim.
