Update the Postgres exporter to the latest version of Postgres exporter community

[Jrmy2402]

Hi,
Do you forecast to update the Postgres exporter to the latest version of Postgres exporter community?
They add valuable metrics like the pg_database_size_bytes, so having this with the Grafana agent could be great.
Thanks

Also interested in this.

I've been trying to figure out why pg_database_size_bytes isn't being reported from integrations/postgres — it didn't occur to me that it simply isn't in grafana-agent yet. :|
