IIRC the main issues are the syntax of CREATE AGGREGATE and the actual implementation in nodeAgg.c. See previous discussions, eg http://archives.postgresql.org/pgsql-general/2006-03/msg00512.php I would really prefer to see CREATE AGGREGATE normalized to have a syntax comparable to CREATE FUNCTION (or DROP AGGREGATE for that matter): CREATE AGGREGATE aggname (typname [, ... ]) ...definition... but it's not clear how to get there without breaking backwards compatibility :-( regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 1: if posting/reading through Usenet, please send an appropriate subscribe-nomail command to [EMAIL PROTECTED] so that your message can get through to the mailing list cleanly
