I've proposed a patch upstream to fix the PostgreSQL part of the warnings:
Warning: postgresql.service changed on disk. Run 'systemctl daemon-reload' to reload units.


However this will not affect the socket ones:
Warning: Stopping foreman.service, but it can still be activated by:
  foreman.socket

Warning: Stopping pulpcore-api.service, but it can still be activated by:
  pulpcore-api.socket

Warning: Stopping pulpcore-content.service, but it can still be activated by:
  pulpcore-content.socket

Those can be fixed if we stop (and start) the sockets in foreman-maintain too. [The stop needs to happen *before* the service stop].

However, I'd argue that this BZ should be split up in two, one fore PostgreSQL (1964394), one for sockets (this one).
