How to set up authorization in nginx by login password stored in Postgresql installed on another server?

Question

PostgreSQL

There are two servers on debian. On one nginx only for uploading files and authorization through nginx with a login-password file. On the other, authorization by login password from postgresql. I would like to make the same logins-passwords for both servers, ideally without re-authorization on another server, or at least using the same login-password.

Answer 1

write a script (for example, in PHP) that will perform authorization and redirect using X-Accell-Redirect

Answer 2
