The question still stands: if the COMMIT fails, ROLLBACK is not required in Postgres. Is this portable to other databases?
I don't think so. I recall messages on this list claiming that some databases (MS SQL, MySQL if memory serves me) commit the queries up to the failed query anyway if you issue a COMMIT (which is just wrong!), so the commit succeeds and there's nothing to rollback after that. Some searching should turn up those messages, if I recall correctly the issue at hand was that people expected that behaviour in Postgres too.
But I don't know what Perl DBI does internally when issuing $dbh- >commit(), maybe it's taking such things into account already.
