We have one query that uses postgis and it returns bytea stuff, so we'll
need to set
as default in our configuration file until the drivers are updated. But
sounds like that's the main issue for us.

Hopefully this will go easy. I haven't run into any problems yet, I'm now
going through the tuning we did for 8.3 and verifying what tuning makes
sense still, but I'm happy to see only a few small bumps in regards to the
JDBC driver.
