I think a documentation correction could be backported without problem to all the currently maintained version of PostgreSQL (which would be of good google value, as very often google searches lands you to previous releases doc pages), whereas a easier to use function would be a new feature and as such could only be introduced in 9.0 or even 9.1. -- Daniele -- Sent via pgsql-bugs mailing list (pgsql-bugs@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-bugs
