Dear Folks,
I am running a full vacuum on a database. It's taking longer than I
hoped. In particular, the vacuum still hasn't reached the table that
will benefit most from the vacuum.
Can I move the existing table to a backup, make a copy of the table
back to its original name, restart the application, and run the vacuum
on the backup? Or can I reclaim the disk space by dropping the
original after making a copy?
If I can, without losing data, what is the best way to do that?
I am reaching the end of the period when this database application can
be disabled.
I have never run vacuum full on such a large database (24G) and am
desperate to get the application back online.
