Monitor Postgress database except version 12

Checkmk Enterprise Edition 2.2.0p12:

Is there a way to monitor a Postgress database that is not version 12? It seems that the agent plugin mk_postgres.py is limited to version 12. I don’t see any reason for this. I currently tested it with version 15 by changing the value _supported_pg_versions to 15 and it worked without any problems

And whats the output when you don’t change the _supported_pg_versions ? Does the plugin display any output at all ?

AFAIK, this was handled here: mk_postgres.py: instances not found under Linux for PostgreSQL version >= 13

Sorry, but I forgot to mention that postgres runs on windows. And no, there is no output at all. It seems to be a problem with line 502 respectively line 135 of /omd/versions/2.2.0p12.cee/share/check_mk/agents/plugins/mk_postgres.py

If you can easily reproduce the problem on Windows, can you send an email to feedback@checkmk.com with your findings ?
