PostgreSQL uses the first matching rule from pg_hba.conf. Presumably
(because that's the default on Debian/Ubuntu) you have it set up to use
peer authentication on the unix socket and password authentication
(scram or md5) on everything else.
You are connecting via the Unix socket (/var/run/postgresql/.s.PGSQL.5432),
so the server will attempt peer authentication and nothing else. To get
it to attempt password authentication connect via a tcp socket:
psql -U my_group_worker -h localhost -d my_group_db
(More conveniently set up ident authentication for your users, then you
don't need a password.)
