In most other scenarios it&#8217;d just be a leak of 10KB that would<br \/>\n    be recovered at end of query, so not too significant; though perhaps the<br \/>\n    leak would be noticeable in a situation where a GIST index was being used<br \/>\n    in a nestloop inner indexscan.  In any case, it&#8217;s a real leak of long<br \/>\n    standing, so patch all supported branches.  Per report from Harald Fuchs.\n<\/p><\/blockquote>\n<p>There were a few fixes for catalog or catalog index corruption, and avoidance of buffer overflows which could cause a backend crash. There were also a few fixes that will improve the performance of VACUUM over time.<\/p>\n<p>Release notes have all the details. Many of the fixes have already been committed to 9.1 (there are only 11 new commits in 9.1.1). So, you&#8217;re about to experience a great many bugfixes, users of 8.2->9.0. <\/p>\n<p>Another thing to note &#8211; 8.2 will be deprecated in 2011! You ought to upgrade anyway, just to get HOT and to get yourself into a position to use pg_upgrade for future upgrades. But now, you&#8217;ve got extra incentive.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Today the Global PostgreSQL Development Group released branch updates for all supported versions.
