Development Versions: [devel](https://www.postgresql.org/docs/devel/view-pg-group.html "PostgreSQL devel - 53.9. pg_group")

The view `pg_group` exists for backwards compatibility: it emulates a catalog that existed in PostgreSQL before version 8.1. It shows the names and members of all roles that are marked as not `rolcanlogin`, which is an approximation to the set of roles that are being used as groups.
