Just on our Wiki pages we have some queries available for copy/paste which would need multiple versions while both column names were in supported versions of the software: http://wiki.postgresql.org/wiki/Lock_dependency_information http://wiki.postgresql.org/wiki/Lock_Monitoring http://wiki.postgresql.org/wiki/Backend_killer_function I agree that these are manageable, but not necessarily trivial.
