indeed my /etc/default/pgbouncer contains `RUNASUSER="pgbouncer"`. I do 
set that explicitly via ansible. However I'm not sure where that line 
originated from. I am quite sure that it's not me who came up with the 
idea of running the daemon as `pgbouncer`, but instead that came from 
the package (which package - if from Debian or from pgdg - I don't know 
I would have to dig further, but maybe I could figure it out).

So what is happening after the introduction of the `.service` file is 
that either `/etc/default/pgbouncer` is now beeing ignored or it is 
being overriden. That breaks installations that had 
`RUNASUSER="pgbouncer"` set in `/etc/default/pgbouncer` when upgrading 
to 1.17.x.

Do you concur with that conclusion?
