## E.327. Release 7.3.12

Release date: 2005-12-12

This release contains a variety of fixes from 7.3.11.

### E.327.1. Migration to Version 7.3.12

A dump/restore is not required for those running 7.3.X. However, if you are upgrading from a version earlier than 7.3.10, see Section E.329.

### E.327.2. Changes

- Fix race condition in transaction log management

  There was a narrow window in which an I/O operation could be initiated for the wrong page, leading to an Assert failure or data corruption.

- `/contrib/ltree` fixes (Teodor)

- Fix longstanding planning error for outer joins

  This bug sometimes caused a bogus error “RIGHT JOIN is only supported with merge-joinable join conditions”.

- Prevent core dump in pg_autovacuum when a table has been dropped
