I have stuck when I will backup my open project tool and get the below error:

Generating database backup...pg_dump: server version: 10.13; pg_dump version: 9.2.24 pg_dump: aborting because of server version mismatch

OS: centos7 Core version: OpenProject 10.6.5 (PostgreSQL)

I'm having the same problem on RHEL.

The issue is that openproject run backup is calling the system-wide default pg_dump, not the pg_dump provided by the postgresql10 package.

I haven't yet figured out how to get openproject to call the correct pg_dump.
