E.25.1. Migration to version 8.0.7

A dump/restore is not required for those running 8.0.X. However, if you are upgrading from a version earlier than 8.0.6, see the release notes for 8.0.6.

E.25.2. Changes

• Fix potential crash in SET SESSION AUTHORIZATION (CVE-2006-0553)

  An unprivileged user could crash the server process, resulting in momentary denial of service to other users, if the server has been compiled with Asserts enabled (which is not the default). Thanks to Akio Ishida for reporting this problem.

• Fix bug with row visibility logic in self-inserted rows (Tom)

  Under rare circumstances a row inserted by the current command could be seen as already valid, when it should not be. Repairs bug created in 8.0.4, 7.4.9, and 7.3.11 releases.

• Fix race condition that could lead to "file already exists" errors during pg_clog and pg_subtrans file creation (Tom)

• Fix cases that could lead to crashes if a cache-invalidation message arrives at just the wrong time (Tom)

• Properly check DOMAIN constraints for UNKNOWN parameters in prepared statements (Neil)

• Ensure ALTER COLUMN TYPE will process FOREIGN KEY, UNIQUE, and PRIMARY KEY constraints in the proper order (Nakano Yoshihisa)

• Fixes to allow restoring dumps that have cross-schema references to custom operators or operator classes (Tom)

• Allow pg_restore to continue properly after a COPY failure; formerly it tried to treat the remaining COPY data as SQL commands (Stephen Frost)

• Fix pg_ctl unregister crash when the data directory is not specified (Magnus)

• Fix ecpg crash on AMD64 and PPC (Neil)

• Recover properly if error occurs during argument passing in PL/python (Neil)

• Fix PL/perl's handling of locales on Win32 to match the backend (Andrew)

• Fix pgxs -L library path specification for Win32, Cygwin, OS X, AIX (Bruce)

• Check that SID is enabled while checking for Win32 admin privileges (Magnus)

• Properly reject out-of-range date inputs (Kris Jurka)

• Portability fix for testing presence of finite and isinf during configure (Tom)
