[BUGS] 7.1beta1 JDBC bug?

[Stu Coates]

I think that I've found a little bug in the 7.1beta1 JDBC drivers.
Attached is a simple test case which produces the problem on my setup
(LinuxPPC 2000, on Apple PowerMac G3-400Mhz, 512MB).  It would seem that
the drivers and/or the DBMS has a problem with nested queries, even
simple ones.

Here's the stacktrace:

Bad Long
  at org.postgresql.jdbc2.ResultSet.getLong(ResultSet.java:284)
  at Test.go(Test.java:35)
  at Test.main(Test.java:15)

I'm using the 7.0.2 JDBC drivers against the 7.1beta1 backend and
everything seems to be working fine.

Stu.
