allow to define sink per metric

[DmitryNFomin]

Hello
I would like to store different metrics in different sinks/storages. Majority of metrics in prometheus, but query texts from pg_stat_statements in postgres, because prometheus does not allow to store texts.
And I can join metrics from different sources (sinks) on grafana dashboard, to show query metrics (like call, and rows) and query text on one dashboard.
I will allow to get best from both storage engines

Probably I didn't find a way to do it and it's already possible

I would go with groups in this case.

$ pgwatch --group=promgroup --sink=prometheus://localhost:9090/

$ pgwatch --group=pggroup --sink=postgresql://../

Then define monitored sources with groups so every instance of pgwatch will fetch only those sources.
