Hi, I would like to access a cpan perl module (FSA::Rules) in a perl procedure, inside Postgresql 8.1.4. FSA::Rules is a library that allows you to define a finite state machine in perl. No disk access. In order to to that, I need to use plperlu instead of plperl. And it works just fine. What exactly is the danger using a cpan library under plperlu? How can I make sure it won't crash my system, even when run concurrently by a few people? Thanks! ---------------------------------- Philippe Lang, Ing. Dipl.
