+       - 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.
+       
+Sun Aug 30 11:33:06 BST 1998
+
+       - 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 <stefan@linux.kapow.dk>
+       - Added fix to DatabaseMetaData.getColumns() to handle patterns
+         submitted by Stefan Andreasen <stefan@linux.kapow.dk>
+       - 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 <jason@idiom.com>
+       - 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
