Looking at the source, I see signs of a caching mechanism in
org.postgresql.Connection.getSQLType(), but at first glance it
seems that this method doesn't actually add the type it
retrieves to its own cache. That could very well be the cause of
the problem.
Do you intend to fix this yourself, or are you seeking help from
this list? If so, it would be nice if you could post a small
program that reproduces the problem. Its probably very simple,
but that way we can be sure we're looking at the same problem.

The CVS system is being migrated and there are lots of posts
about it on the pgsql-hackers list. I'm not sure what the latest
status is. The latest information should be on
http://developer.postgresql.org/, but because of the recent
shutdown of Great Bridge the system is in flux.
