Yes, I've seen that. Apparently the latest 1.6 introduces the JDBC 4
standard. It in turn, adds some new methods. I'll look into that with
the intention to create dummy implementations that throw unsupported
feature exceptions for now. The actual JDBC 4 will have to wait a while
longer.

This is likely to be a consequence of earlier compilation errors.

It's there, but it's broken.

I suggest you revert to Java 1.5 for now and rebuild your postgresql
using 'configure --without-zlib' to avoid the zlib issue.
