Here’s a fairly objective metric for comparing the complexity of deploying Jenkins vs Postgres:

https://github.com/geerlingguy/ansible-role-jenkins

https://github.com/geerlingguy/ansible-role-postgresql

Two ansible roles by the same author, supporting both Centos and Ubuntu. Not hugely different in complexity IMO. Installing Postgres on FreeBSD, though, is little more than

    pkg install postgresql10-server
    sysrc postgresql_enable=“YES”
    service postgresql initdb
    service postgresql start

I get that they install differently, but that's not the point. The point is that they do very different things, in different ways. Postgres is not a Jenkins replacement. Postgres is storage and querying. Its equivalent on Jenkins is XML files.
