As of version 2.1.0p30 and 2.2.0p4, it was no longer possible to use the plugin postgres_instances, if the instance name was empty. In previous versions, this plugin would show a service with the item PostgreSQL Instance . This service would be OK, if there was at least one process belonging to any postgres instance, and CRIT otherwise.

With this Werk, the plugin postgres_instances no longer crashes, if there is an empty instance name. The old service PostgreSQL Instance is no longer discovered. Instead the new check plugin postgres_processes can be used.
