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?
cron job to check for tables without PK ? Although for a short period the
offending table would be there live without a PK.
But IMO every table, in addition to PK, should have also natural unique keys as
much as possible.
Better safe than sorry.
Thanks,
