The version detection for the server did not use the configured database, user and port defined in the postgres.cfg. Instead the default values were used. If the plugin cannot execute queries with the default values the plugin will exit prematurely.

To resolve the issue the fixed version of the mk_postgres plugin has to be deployed on the affected hosts.
