E.83. Release 9.1.2

Release Date: 2011-12-05

This release contains a variety of fixes from 9.1.1. For information about new features in the 9.1 major release, see E.85절.

E.83.1. Migration to Version 9.1.2

A dump/restore is not required for those running 9.1.X.

However, a longstanding error was discovered in the definition of the information_schema.referential_constraints view. If you rely on correct results from that view, you should replace its definition as explained in the first changelog item below.

Also, if you use the citext data type, and you upgraded from a previous major release by running pg_upgrade, you should run CREATE EXTENSION citext FROM unpackaged to avoid collation-related failures in citext operations. The same is necessary if you restore a dump from a pre-9.1 database that contains an instance of the citext data type. If you've already run the CREATE EXTENSION command before upgrading to 9.1.2, you will instead need to do manual catalog updates as explained in the second changelog item.
