The rollback only takes place on the errored statement, because you are catching the exception.
In order to ensure a complete rollback of your transaction (which may have started outside of your function),
you'll need to rethrow an error after your exception handling.
In order to store a corresponding message within a table, you'll need a separate transaction which can be achieved,
- as already mentioned- with dblink. Possibly some <pg>_fwd extensions allow this too, I don't know.
