These are two MAJOR RELEASES (which allow for API changes) apart (i.e., one major release in between - 9.1) The release notes for 9.2 note this particular change explicitly: http://www.postgresql.org/docs/9.2/interactive/release-9-2.html Section E.9.2.6 Note the presence of the "state" column in the 9.2 schema - you use this to determine if a connection is "idle" instead of looking for "<IDLE>" in a query column which then allows the query column to be report the "last known query" at all times.
