Re: Relpages not being recovered?

Actually, I thought a VACUUM or VACUUM ANALYZE would provide the results I wanted.

After I realized my error, a VACUUM FULL gave me what I needed and problem solved.

Thanks for the help though!

I can assure you that relpages is correct after a vacuum --- look at the
physical file for the table if you want to confirm it.

The answer you are probably really looking for is some combination of
more-frequent vacuums and increasing your FSM configuration parameters
so that free space in the table is recycled more effectively. Try
searching the list archives for "free space map".
