I am trying to back up my database using pg_dump from the psql client, following the instructions provided in the following link:
https://blog.railway.com/p/postgre-backup.

However, when executing the command, I encounter the following error:

pg_dump: error: server version: 16.4 (Debian 16.4-1.pgdg120+2); pg_dump version: 14.15 (Ubuntu 14.15-0ubuntu0.22.04.1)

pg_dump: error: aborting because of server version mismatch

The same error occurs when trying to use the backup tools in pgAdmin 4.
