Note that I have avoided using the "performance" word for this very reason. But consider for example when the datum type is PLPGSQL_DTYPE_REC. I dont think its justified to have the overhead of heap_copytuple_with_tuple, when all we need is just the typeid! Similar arguments apply for other datums like PLPGSQL_DTYPE_ROW, PLPGSQL_DTYPE_TRIGARG e.g. Regards, Nikhils -- EnterpriseDB http://www.enterprisedb.com
