Release Date: 2009-12-14
This release contains a variety of fixes from 8.0.22. For information about new features in the 8.0 major release, see Section E.167.
A dump/restore is not required for those running 8.0.X. However, if you are upgrading from a version earlier than 8.0.22, see Section E.145.
Protect against indirect security threats caused by index functions changing session-local state (Gurjeet Singh, Tom)
This change prevents allegedly-immutable index functions from possibly subverting a superuser's session (CVE-2009-4136).
Reject SSL certificates containing an embedded null byte in the common name (CN) field (Magnus)
This prevents unintended matching of a certificate to a server or client name during SSL validation (CVE-2009-4034).
Fix possible crash during backend-startup-time cache initialization (Tom)
Prevent signals from interrupting VACUUM at unsafe times (Alvaro)
This fix prevents a PANIC if a VACUUM FULL is canceled after it's already committed its tuple movements, as well as transient errors if a plain VACUUM is interrupted after having truncated the table.
Fix possible crash due to integer overflow in hash table size calculation (Tom)
This could occur with extremely large planner estimates for the size of a hashjoin's result.
Fix very rare crash in inet/cidr comparisons (Chris Mikkelson)
Fix premature drop of temporary files used for a cursor that is accessed within a subtransaction (Heikki)
Fix PAM password processing to be more robust (Tom)
The previous code is known to fail with the combination of the Linux pam_krb5 PAM module with Microsoft Active Directory as the domain controller. It might have problems elsewhere too, since it was making unjustified assumptions about what arguments the PAM stack would pass to it.
Fix rare crash in exception processing in PL/Python (Peter)
Ensure psql's flex module is compiled with the correct system header definitions (Tom)
This fixes build failures on platforms where --enable-largefile causes incompatible changes in the generated code.
Make the postmaster ignore any application_name parameter in connection request packets, to improve compatibility with future libpq versions (Tom)
Update time zone data files to tzdata release 2009s for DST law changes in Antarctica, Argentina, Bangladesh, Fiji, Novokuznetsk, Pakistan, Palestine, Samoa, Syria; also historical corrections for Hong Kong.
