      Make <code class="function">pg_options_to_table</code> return NULL for an option with no
      value (Tom Lane)
     </p><p>
      Previously such cases would result in a server crash.

      Fix memory leak at end of a GiST index scan (Tom Lane)
     </p><p>
      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.
     </p></li><li class="listitem"><p>
      Fix explicit reference to <code class="literal">pg_temp</code> schema in <code class="command">CREATE
      TEMPORARY TABLE</code> (Robert Haas)
     </p><p>
      This used to be allowed, but failed in 9.1.0.
