Data Corruption Fix

For users of PostgreSQL versions 9.3 or 9.4, this release fixes a problem where
the database will fail to protect against "multixact wraparound", resulting in
data corruption or loss. Users with a high transaction rate (1 million or more
per hour) in a database with many foreign keys are especially vulnerable. We
strongly urge all users of 9.4 and 9.3 to update their installations in the
next few days.

Earlier update releases attempted to fix an issue in PostgreSQL 9.3 and 9.4
with "multixact wraparound", but failed to account for issues doing multixact
cleanup during crash recovery. This could cause servers to be unable to restart
after a crash. As such, all users of 9.3 and 9.4 should apply this update as
soon as possible. Users of versions 9.2 and earlier are not affected by this issue.
