Обсуждение: verifying database integrity?

Hi -- Some clod turned off the power to my customer's computer -- a Linux
box with a Postgres server on it -- while it was running.  Ever since then,
certain PostgreSQL queries have been very slow.  We wonder how to tell if
the database was damaged.  Is there a program we can run to check the
integrity of the database?  (And is this the right list for me to ask this
question on?)

Thanks in advance...

Rebuild your indices.
Run vacuum verbose.

Vacuuming did the trick.  I don't know how I managed not to find out that
we should have been vacuuming regularly.  I've set up a cron job to do it
nightly.  We had been tearing our hair out over this.  Many many thanks!!
