The problem here is that the pgjdbc people dropped their debug methods
in favour of the java.util.logging framework. I committed a patch to
fix this, but that means that we won't compile on java 1.3 and earlier
any more.

This is because the PGJDBC people kept changing their interface for
datatype extensions, and I've to support it back to 7.2.

So I use some ugly classloader tricks and a custom stub to make it work.

Things would be much easier here if we could support only pgjdbc 8.0 and
newer (which would still work against older servers)

Now, it seems that GCJ does not get the classpath correct, when the
classpath has components relative to the current directory, and uses the
original PGJDBC classes instead.

I committed a small makefile patch that should fix it.

Thanks,
Markus
