I suspect it's an oversight, because the comment gives no hint that any such intention was present. It's been more than three years since I committed that code (under a different function name) so my memory is a little fuzzy, but I believe it just didn't occur to me that MinMaxExpr could include a function call. I suspect it's safe in practice, but in theory it's probably a bug. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
