Thanks for this suggestion, but I think this does not solve the issue,
since according to the docs, the validity of a constraint should be
checked after each statement unless this behaviour is altered with a SET
CONSTRAINTS statement.
Anyway, the select f(); is in my case not executed in transactional
context (not embraced by START TRANSACTION; ... COMMIT;).

Christian
