Bruce,

Attached is a patch which patches cleanly against the Sunday afternoon
snapshot. It modifies pg_dump to dump COMMENT ON statements for
user-definable descriptions. In addition, it also modifies comment.c so
that the operator behavior is as Peter E. would like: a comment on an
operator is applied to the underlying function.

Thanks,

Mike Mascari
