This is a bug-fix release for 6.3.x. Refer to the release notes for version 6.3 for a more complete summary of new features.
Repairs automatic configuration support for some platforms, including Linux, from breakage inadvertently introduced in version 6.3.1.
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 PostgreSQL libraries.
For upgrades from pre-6.3 installations, refer to the installation and migration instructions for version 6.3.
