Works for me: regression=# create table a (A_primary_col int primary key); NOTICE: CREATE TABLE / PRIMARY KEY will create implicit index "a_pkey" for table "a" CREATE TABLE regression=# insert into a values (1),(2),(3); INSERT 0 3 regression=# create table b (B_primary_col text primary key, a_reference int references a on delete cascade); NOTICE: CREATE TABLE / PRIMARY KEY will create implicit index "b_pkey" for table "b" CREATE TABLE regression=# insert into b values('A',1),('B',2),('C',3); INSERT 0 3 regression=# DELETE FROM A; DELETE 3 regression=# select * from a; a_primary_col --------------- (0 rows) regression=# select * from b; b_primary_col | a_reference ---------------+------------- (0 rows) regression=# insert into a values (4); INSERT 0 1 regression=# insert into b values('A',4); INSERT 0 1 I suspect a mistake on your part. If you can actually reproduce this problem, please show an exact test case, not hand-waving. regards, tom lane -- Sent via pgsql-bugs mailing list (pgsql-bugs@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-bugs
