PostgreSQL 8.4 Release Candidate 1 Now Available

News source: PostgreSQL

"Posted on 2009-06-14
Posted by press@postgresql.org

Final release of PostgreSQL 8.4 comes much closer today with our first Release Candidate. Now, we count on all of the PostgreSQL users and developers worldwide to test this Release Candidate to make sure that it is stable, reliable, secure and high-performance enough to be called an official PostgreSQL release. Please download 8.4 RC1 today and test it with your applications.

Beta testing information page and download links

Note that no Windows MSI installer will be released for this Release Candidate. Windows users are advised to use the One-Click Installer instead.

Several of the issues patched in this release relate to pg_migrator, the new beta in-place upgrade tool for upgrading PostgreSQL databases. Please test migrating a copy of your 8.3 databases to 8.4 and report further issues with pg_migrator, especially issues related to Additional Modules (contrib). pg_migrator will release version RC1 soon which will be compatible with 8.4 RC1, and you can get it on pgFoundry.

This Release Candidate also includes a number of changes to handling of NULL inputs to internal functions in order to prevent denial-of-service exploits. First, the general internal_in() function is now NONSTRICT in order to trap NULL errors for debugging. Second, several internal functions in our Additional Modules have been marked STRICT to lock them down, especially several GiST index functions and pg_freespacemap. Please check for unanticipated side-effects of this more secure policy for internal functions against your application, especially if you use PostgreSQL plug-ins like GIS and BLAST.

Other specific items fixed since Beta2 Include:

-- Fix FreeBSD Kerberos support
-- Fix row ordering on scrollable and WITH HOLD cursors
-- Make datetime precision in INFORMATION_SCHEMA comply with the standard
