Vacuum clarifications/issues

Hi,

I'm vacuming a table containing 300,000 rows with a single index.
Currently it is taking 1.5 hours to complete. It was faster earlier.
I have dropped and recreated and reloaded this table. THis does not seem to
help.

Further... vacuum returns several messages.... like crashed... unused...
moved etc.,
Some of them have numbers.
Can anybody tell me what I should do with these and how to interpret them
etc.,

Thanks,

Murali
