This should probably have been posted to the novice, sql, or general
mailing as well, BTW. But that is also mentioned in the on-line pages: ;-)

http://www.postgresql.org/lists.html

"This list is for the discussion of current development issues,
problems and bugs and the discussion of proposed new features.

If people in the other lists don't know the answer to a question and
it is likely that only a developer will know the answer, you may
re-post that question here. You must try elsewhere first!"
