Custom Tables using Postgres integration

I’ve followed the guide and I am curious if there’s a way to use custom table names, and only pull out specific data. The way it is installed there gives me way more data than I want to use and it would help a ton to be able to limit it. Does anyone have experience doing this?

I think you would be better off using a HTTP integration with a small (PHP?) script to selectively write wanted data to a PSQL db.
