Should this produce a warning? nconway=# create table a (b int4 unique); NOTICE: CREATE TABLE / UNIQUE will create implicit index "a_b_key" for table "a" CREATE TABLE nconway=# create table c (d int8 references a (b)); NOTICE: CREATE TABLE will create implicit trigger(s) for FOREIGN KEY check(s) CREATE TABLE
Aside from the logical inconsistency, it will also lead to poor performance since the type mismatch will prevent index scans. I've noticed a couple people have reported performance issues due to making this kind of mistake. -Neil ---------------------------(end of broadcast)--------------------------- TIP 7: don't forget to increase your free space map settings
