Wrapping TypeGetTupleDesc(typoid, NIL) is very specific, and probably this code should be inside the extension. Different question is API for searching in system catalog and dependencies. I can imagine some functions like Oid extid = get_extension_id(extname); Oid objid = get_extension_object_id(extid, schema_can_be_null, name, TYPEOID); // can be used for routine, table, ... tupdesc = TypeGetTupleDesc(objid, NIL); Regards Pavel
