Well, if you upgrade your database to Postgres, we might be able to help you.
Either way, I'd suggest the pgsql-jdbc list instead of this one.
I think, however, that the simplest answer is right in front of your face:
"Transaction Isolation Levels are not supported." poolman apparently relies
on the jdbc driver to manage transactional isolation. The jdbc driver
doesn't, which means that your connection pooler can't use it. So of course
it barfs. Of course since MySQL doesn't support transactions, you're
probably not going to be able to find a jdbc driver which does.
Moral of the story? Get a real database.
