Some more including the patch to DatabaseMetaData backed out by Bruce.

Tue Feb 13 16:33:00 GMT 2001 peter@retep.org.uk
        - More TestCases implemented. Refined the test suite api's.
        - Removed need for SimpleDateFormat in ResultSet.getDate() improving
          performance.
        - Rewrote ResultSet.getTime() so that it uses JDK api's better.

Tue Feb 13 10:25:00 GMT 2001 peter@retep.org.uk
        - Added MiscTest to hold reported problems from users.
        - Fixed PGMoney.
        - JBuilder4/JDBCExplorer now works with Money fields. Patched Field &
          ResultSet (lots of methods) for this one. Also changed cash/money to
          return type DOUBLE not DECIMAL. This broke JBuilder as zero scale
          BigDecimal's can't have decimal places!
        - When a Statement is reused, the previous ResultSet is now closed.
        - Removed deprecated call in ResultSet.getTime()

Thu Feb 08 18:53:00 GMT 2001 peter@retep.org.uk
        - Changed a couple of settings in DatabaseMetaData where 7.1 now
          supports those features
        - Implemented the DatabaseMetaData TestCase.

Wed Feb 07 18:06:00 GMT 2001 peter@retep.org.uk
        - Added comment to Connection.isClosed() explaining why we deviate from
          the JDBC2 specification.
        - Fixed bug where the Isolation Level is lost while in autocommit mode.
        - Fixed bug where several calls to getTransactionIsolationLevel()
          returned the first call's result.
