Postgres jdbc3 or jdbc4 driver support? [message #509319]

Postgres 8.4 requires jdbc3 or jdbc4 driver, but the database connection wizard in dtp seems to require the jdbc2 driver. Is this a known limitation or am I doing something wrong?

Following occurs trying to use jdbc4 driver in Galileo on Windows:

Unfortunately we don't have any Postgres-specific knowledge on the team
any more. We'd love to have someone with Postgres know-how take a look
and contribute patches for anything they find though...

This means normalls that you JVM is too old and that the *.jar/*.clas requires a
newer JVM.
