E.255. Release 7.3.12

E.255.1. 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.257.

E.255.2. 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
