E.72. Release 9.1.1

E.72.1. Migration to Version 9.1.1

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

E.72.2. Changes

• Make pg_options_to_table return NULL for an option with no value (Tom Lane)

  Previously such cases would result in a server crash.

• Fix memory leak at end of a GiST index scan (Tom Lane)

  Commands that perform many separate GiST index scans, such as verification of a new GiST-based exclusion constraint on a table already containing many rows, could transiently require large amounts of memory due to this leak.

• Fix explicit reference to pg_temp schema in CREATE TEMPORARY TABLE (Robert Haas)

  This used to be allowed, but failed in 9.1.0.
