What about having no internal arguments here at all? Like if you want to support foo[4] define a subscript function that takes (mytype, int) and returns whatever. You might have to allow for multiple subscripting functions with different argument types for this to really work, though. /me ducks -- 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
