+   - removed syncronised from Connection.ExecSQL(). See next entry.
+   - added new syncronised locking in the Connection.ExecSQL() and
+     FastPath.fastpath() methods. They now lock against the PG_Steam
+     object for the connection, which now provides full Thread Safety.
+   - Reposted ChangeLog as it's missing from CVS.
+   
+Modifications done since 6.3.2 was released and Sun Aug 30 11:33:06 BST 1998
+
+   - Fixed PreparedStatement.setObject as it didn't handle shorts
+   - ResultSet.getDate() now handles null dates (returns null ratrher
+     than a NullPointerException)
+   - ResultSetMetaData.getPrecision() new returns 0 for VARCHAR
+   - Field now caches the typename->oid in a Hashtable to speed things
+     up. It removes the need for some unnecessary queries to the backend.
+   - PreparedStatement.toString() now returns the SQL statement that it
+     will send to the backend. Before it did nothing.
+   - DatabaseMetaData.getTypeInfo() now does something.
+   - Connection now throws an exception if either of the user or password
+     properties are missing, as they are required for JDBC to work.
+     This occasionally occurs when the client uses the properties version
+     of getConnection(), and is a common question on the email lists.
+

+
+   - Created ChangeLog file, and entered stuff done since 6.3.2 and today
+   - Change version number to 6.4 in Driver.java
+   - Added fix to DatabaseMetaData.getTables() submitted by
+     Stefan Andreasen 
+   - Added fix to DatabaseMetaData.getColumns() to handle patterns
+     submitted by Stefan Andreasen 
+   - Set TcpNoDelay on the connection, as this gives us a 10x speed
+     improvement on FreeBSD (caused by a bug in their TCP Stack). They
+     should fix the bug before 6.4 is released, but will keep this
+     in here unless it causes more problems.
+     Submitted by Jason Venner 
+   - Removed a duplicate definition of fieldCache
+   - Added a more meaningful message when the connection is refused. It
+     now says:
+       Connection refused. Check that the hostname and port is
+       correct, and that the postmaster is running with the -i flag,
+       which enables TCP/IP networking.
+   - Removed kludge in PreparedStatement.setDate() that acted as a
+     temporary fix to a bug in SimpleDateFormat, as it broke date
+     handling in JDK 1.1.6.
+   - Modified PG_Stream and Connection, so that outbound data is now
+     buffered. This should give us a speed improvement, and reduce the
+     ammount of network packets generated.
+   - Removed duplicate code and optimised PG_Stream.
+   - PG_Stream now returns a more meaningful message when the connection
+     is broken by the backend. It now returns:
+       The backend has broken the connection. Possibly the action you
+       have attempted has caused it to close.
+   - Removed obsolete code from Connection.
+   - The error message returned when the authentication scheme is unknown
+     has been extended. It now reads:
+       Authentication type ### not supported. Check that you have
+       configured the pg_hba.conf file to include the client's IP
+       address or Subnet, and is using a supported authentication
+       scheme.
+   - Connection.getMetaData() now caches the instance returned, so
+     multiple calls will return the same instance.
+   - Created a test application that tests the DatabaseMetaData and
+     ResultSetMetaData classes.
+   - Replaced getString(#).getBytes() with getBytes(#) which should speed
+     things up, and reduce memory useage.
+   - Optimised DatabaseMetaData.getProcedures(), and implemented patterns
+   - Fixed NullPointerExceptions thrown when a field is null (Internal
+     to the driver, not caused by results from the backend.
+     DatabaseMetaData.getProcedures() is an example of a method that
+     causes this):
+       - ResultSetMetaData.getColumnName() now returns field# where
+         # is the column name.
+       - ResultSet.getObject() fixed
+       - Fixed bug in psql example that was affected by null fields
+       - DatabaseMetaData.getTables()
+   - DatabaseMetaData.getPrimaryKeys() ran a query with an ambiguous field
+     fixed.
+   - getTypeInfo() optimised to increase speed and reduce memory useage
+   - ResultSetMetaData.isCurrency() optimised and is now smaller.
+   - Removed unnecessary code fromResultSetMetaData.getCatalogName()
+     and getSchemaName().
+   - Created new class postgresql.util.PGmoney to map the money type
+   - Created new class postgresql.geometric.PGline to map the line type
