Datum does not carry any type information, only a value. Functions are typically coded to know their input types a priori. If you want to write code that is not type-specific then you'd better be passing around type OIDs as well as values. regards, tom lane -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
