Running the JDBC driver's regression test suite for the first time in a
while I got a lot of failures that I would have to guess are related to
plan invalidation work. Attached is a self contained test case and the
JDBC driver's log of what protocol messages it is sending.
The end result is:
ERROR: cache lookup failed for type 2139062143
