Well, that simplifies things. First off, what does it say for rows affected? (Hint, if you really are using a default configuration and it doesn't say 0 rows affected, please show us the actual query used.) Second, try connecting to the database as a superuser and running: VACUUM ANALYZE imports; -- (show us the results) VACUUM FULL imports; VACUUM FREEZE ANALYZE; -- (don't specify a table) Then try your query and see whether performance is any different. -Kevin -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
