Обсуждение: Deleting a rule?

I wrote a rule a while back that, due to the software being extended, now
needs to be deleted.

How do I drop a rule?

    DELETE FROM pg_rules WHERE rulename='foo';

doesn't seem to cut it...

With DROP RULE.  Here's a link to the documentation for the latest
release:

http://www.postgresql.org/docs/8.0/static/sql-droprule.html

If that doesn't work then please provide more info.

In general, you don't probably want to be mucking around in the
system catalog (the pg_* tables) unless you know what you're doing.
Most of the things that need to be done have specific commands so you
don't have to work with the system tables directly.

You'll also probably find the SQL Command Reference page helpful.

Hope this helps.
