Additional support for multibyte character sets.
Repair byte ordering for mixed-endian clients and servers.
Minor updates to allowed SQL syntax.
Improvements to the configuration autodetection for installation.
A dump/restore is NOT required for those running 6.3. A make distclean, make, and make install is all that is required. This last step should be performed while the postmaster is not running. You should re-link any custom applications that use PostgreSQL™ libraries.
For upgrades from pre-6.3 installations, refer to the installation and migration instructions for version 6.3.
