This is a bugfix release for 6.3.x. Refer to the release notes for v6.3 for a more complete summary of new features.
Summary:
Repairs automatic configuration support for some platforms, including Linux, from breakage inadvertently introduced in v6.3.1.
Correctly handles function calls on the left side of BETWEEN and LIKE clauses.
A dump/restore is NOT required for those running 6.3 or 6.3.1. 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 Postgres libraries.
For upgrades from pre-v6.3 installations, refer to the installation and migration instructions for v6.3.
