[2.3.0] Checkmk Werk 15644 created: postgres_processes: Restore Monitoring if Instance Name is Missing

Title: postgres_processes: Restore Monitoring if Instance Name is Missing Class: fix Compatible: compat Component: checks Date: 1695383436 Edition: cre Knowledge: doc Level: 1 Version: 2.3.0b1 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, i.e. ``. 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.
