# E.5. Release 9.1.1

> Release Date: 2011-09-26

This release contains a small number of fixes from 9.1.0. For information about new features in the 9.1 major release, see Section E.6.

## E.5.1. Migration to Version 9.1.1

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

## E.5.2. 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.
