Breakage: pgbouncer has changed the user under which it runs between 1.16.1 and 1.17.0

Dear packagers,

Due to the change of user under which pgbouncer runs (before: user 
pgbouncer, new: user postgres), an upgrade from 1.16.1 to 1.17.0 will 
break systems.

     # cat /var/log/apt/history.log
     [...]
     Upgrade: pgbouncer:amd64 (1.16.1-1.pgdg20.04+1,
              1.17.0-3.pgdg20.04+1)

     # cat /etc/apt/sources.list.d/apt_postgresql_org_pub_repos_apt.list
     deb http://apt.postgresql.org/pub/repos/apt/ focal-pgdg main

Workaround:

     # chown postgres.postgres /etc/pgbouncer/*
     # # the next line depends on where pgbouncer is set up to save
     # # its logs go - see /etc/pgbouncer/pgbouncer.ini
     # chown -R postgres.postgres /var/log/pgbouncer/
     # # see preceeding comment
     # chown postgres.postgres /var/log/postgres/pgbouncer*
     # chown -R postgres.postgres /var/run/pgbouncer

I've originally reported that [here] and was redirected to this mailing 
list.

Thanks a lot for the packages & greetings,
*t
