[Haskell-cafe] Yesod app uses wrong port when connecting to PostgreSQL

Hi folks! I'm struggling with following error: libpq: failed (could not connect to server: Connection refused Is the server running on host "localhost" (127.0.0.1) and accepting TCP/IP connections on port 5432? I see such messages in Keter's log (in app folder). The VPS where the app deployed running PostgreSQL 9.6 on port 5433. I have changed default port in: - config/settings - config/keter.yaml - /opt/keter/etc/postgres.yaml on server side None of these steps helped. I wasn't able to find other port configuration places. What else can I do?
