--- title: "pg_group" id: view-pg-group pg_version: "20devel" --- ## 53.10. 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. **pg_group Columns** | Column Type | Description | | --- | --- | | `groname` `name` (references [pg_authid](catalog-pg-authid.md).`rolname`) | Name of the group | | `grosysid` `oid` (references [pg_authid](catalog-pg-authid.md).`oid`) | ID of this group | | `grolist` `oid[]` (references [pg_authid](catalog-pg-authid.md).`oid`) | An array containing the IDs of the roles in this group |
