Hi all,I have a table accgroups and many others. I have written a test function as follows. CREATE OR REPLACE FUNCTION uf_testfunction() RETURNS SETOF associates AS $BODY$ begin return query select * from associates; return; end; $BODY$ LANGUAGE 'plpgsql' VOLATILE; This works fine for above table but not works at all for accgroups table. As I searched for this over web, it is identified as a bug for tables whose columns are changed(deleted and added). Is it true? How to solve this issue? Thanks CPK
