Log Message:
Update PostgreSQL 8.0.x to 8.0.7.

The fix for locales and plperl in 8.0.6 might make an REINDEX necessary.

Changes from 8.0.5 to 8.0.6:
- Fix Windows code so that postmaster will continue rather than exit if
there is no more room in ShmemBackendArray (Magnus)
- Fix bug introduced in 8.0 that could allow ReadBuffer to return an
already-used page as new, potentially causing loss of recently-committed
data (Tom)
- Fix for protocol-level Describe messages issued outside a transaction
or in a failed transaction (Tom)
- Fix character string comparison for locales that consider different
character combinations as equal, such as Hungarian (Tom)
- Set locale environment variables during postmaster startup to ensure
that plperl won't change the locale later
- Allow more flexible relocation of installation directories (Tom)
- Fix longstanding bug in strpos() and regular expression handling in
certain rarely used Asian multi-byte character sets (Tatsuo)
- Various fixes for functions returning RECORDs (Tom)
- Fix bug in /contrib/pgcrypto gen_salt, which caused it not to use all
available salt space for MD5 and XDES algorithms (Marko Kreen, Solar
Designer)
- Fix /contrib/dblink to throw an error, rather than crashing, when the
number of columns specified is different from what's actually returned
by the query (Joe)

Changes from 8.0.6 to 8.0.7:
- Fix potential crash in SET SESSION AUTHORIZATION (CVE-2006-0553)
- Fix bug with row visibility logic in self-inserted rows (Tom)
- 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

postgresql.conf on Win32 (Bruce)

(Bruce)
- Check that SID is enabled while checking for Win32 admin privileges
(Magnus)
- Properly reject out-of-range date inputs (Kris Jurka)

configure (Tom)
