How to hide tables for the user?

Question

PostgreSQL

Good afternoon.
They didn’t ban me on Google - I didn’t find the information.
Created a user who needs to be given access to only a few views in the database.
The problem is that he can really view the content of only these views, but at the same time he sees tables that he should not (without the ability to view data)
And also sees other databases on this server (also without viewing the content)
Tell me how to hide other databases and tables from the user on server?

Answer 1

No way.

Answer 2

Write a simple rest service and provide it with an endpoint (s) that return data only from these views?
