Re: isNullable()

Attached is a patch that fixes ResultSetMetaData.isNullable() in
the JDBC driver.

This method is currently unimplemented and always returns
ResultSetMetaData.columnNullable. This is obviously incorrect
when a column is defined with NOT NULL or PRIMARY KEY. And we
have to think of check constraints, views, functions etc.

The patch simply changes the return value to
ResultSetMetaData.columnNullableUnknown. This is until someone
comes up with a real implementation of course.
