It's not really a bug, but it is quite annoying. > CREATE FUNCTION t1_part_test_trigger() > RETURNS TRIGGER AS $$ > BEGIN > IF NEW.id >= 1 AND NEW.id <= 1000 THEN > INSERT INTO t1_part_01 VALUES (NEW.*); > ELSIF NEW.id > 1000 AND NEW.id <= 22000000 THEN > INSERT INTO t1_part_02 VALUES (NEW.*); > END IF ; > RETURN NULL; > END; > $$ > LANGUAGE plpgsql; The problem is here. You returned null in a BEFORE trigger which cancels the insert. As far as PostgreSQL is concerned, you didn't insert anything into this table (because you didn't) and so it correctly but annoyingly returns 0. > hba=> insert into t1_part values (3000001, '3000001' ) ; > INSERT 0 0 -- should be “INSERT 0 1” To get this effect, which I believe is required for Hibernate and some other frameworks, you need to create a view with an INSTEAD OF trigger that inserts into the table, which then get rerouted with your BEFORE trigger. Then you insert into the view and get the desired result. -- Vik Fearing +33 6 46 75 15 36 http://2ndQuadrant.fr PostgreSQL : Expertise, Formation et Support -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
