Redash offer this as a feature[1]. Their product starts at $49 per month for unlimited users with up to three data sources from a wide range[2], not just Postgres.

I think the Google Sheets export is very valuable, it opens up data to non-developer analysts and general business users. But I also can't see how this product is competitive at this price with only this functionality.
