Views are like C macros for you query...they are expanded first and then planned. Functions (except for very simple ones) are black boxes to the planner and can materially hurt query performance in common cases. The only case where a function would win is when dealing with conner case planner issues (by forcing a nestloop for example). merlin -- Sent via pgsql-performance mailing list (pgsql-performance@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
