That was what I started to write, too, but actually I think the IS DISTINCT is correct and the RIGHT JOIN should be a LEFT JOIN. Note that the query appears to be intended to collect regular tables as well as indexes. (As patched, that's totally broken, so I infer Bruce hasn't tested it yet.) regards, tom lane -- Sent via pgsql-hackers mailing list (email@example.com) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
