As the email posted to the announce and interfaces list, attached is a tar

file containing the latest version of the JDBC driver, allowing it to be
compiled and used under JDK 1.2 and later.

NB: None (well almost none) of the new methods actually do anything. This
release only handles getting it to compile and run. Now this is done, I'll
start working on implementing the new stuff.

Now this tar file replaces everything under src/interfaces/jdbc. I had to
do it this way, rather than diffs, because most of the classes under the
postgresql subdirectory have moved to a new directory under that one, to
enable the support of the two JDBC standards.

Here's a list of files in the tar file. Any file not listed here (in the
postgresql directory) will have to be deleted, otherwise it could cause
the driver to fail:
