## E.311. Release 7.2.6

Release date: 2004-10-22

This release contains a variety of fixes from 7.2.5.

### E.311.1. Migration to Version 7.2.6

A dump/restore is not required for those running 7.2.X.

### E.311.2. Changes

- Repair possible failure to update hint bits on disk

  Under rare circumstances this oversight could lead to “could not access transaction status” failures, which qualifies it as a potential-data-loss bug.

- Ensure that hashed outer join does not miss tuples

  Very large left joins using a hash join plan could fail to output unmatched left-side rows given just the right data distribution.

- Disallow running pg_ctl as root

  This is to guard against any possible security issues.

- Avoid using temp files in /tmp in make_oidjoins_check

  This has been reported as a security issue, though it's hardly worthy of concern since there is no reason for non-developers to use this script anyway.

- Update to newer versions of Bison
