You really need to be more specific about where you need this information. The "sorting code" certainly knows what datatypes it's working with --- for example, in tuplesort.c there's a TupleDesc for the tuples passing through the sort, and the column types are available from the per-column atttypid fields of that. But it's not clear if that's what you're talking about. regards, tom lane -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
