Default pg_exporter.yaml question

[Idosegal]

In case I want to use the default pg_expoeter.yaml, but I want to add a custom query. Do I need to store the whole default yaml with my additional query?
Is it possible just to add the delta to a file and other will be taken from the default?

You can have multiple configuration files, you just need to specify the path to the directory where your yaml files are located, the exporter will read all yaml files in that specific directory and load all the metrics from those files.

-c, --config=CONFIG path to config dir or file

IMO this is the best way to have your custom metrics in separate files.
