This works for me in the current minor release (15.5):
$ psql
psql (15.5)
Type "help" for help.
postgres=# ALTER TABLE IF EXISTS ONLY public.foo DROP CONSTRAINT IF EXISTS foo_pkey;
NOTICE: relation "foo" does not exist, skipping
ALTER TABLE
Please update. If you can still reproduce the problem in the
current release, there must be some additional contributing
factor -- please try to provide a self-contained test case.
