Oh, I see. That's fine with me. From the source code it's hard to see when a SQL-callable function is only there to implement an operator, though (and it seems a bit far-fetched to suppose that the developer will think, upon seeing an undocumented function, "oh this must implement some operator, I will look it up at pg_proc.h"). I think the operator(s) should be mentioned in the comment on top of the function. -- Álvaro Herrera http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Training & Services -- Sent via pgsql-hackers mailing list (email@example.com) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
