We want to enforce a policy, partly just to protect those who might forget, for every table in a particular schema to have a primary key. This can't be done with event triggers as far as I can see, because it is quite legitimate to do:
BEGIN;
CREATE TABLE foo (id int);
ALTER TABLE foo ADD PRIMARY KEY (id);
COMMIT;
It would be nice to have some kind of "deferrable event trigger" or some way to enforce that no transaction commits which added a table without a primary key.
Any ideas?
Thanks,
Jeremy
