This catalog defines groups and stores what users belong to what
groups. Groups are created with the CREATE
GROUP command. Consult the Administrator's
Guide for information about user permission management.
Because user and group identities are cluster-wide,
pg_group
is shared across all databases of a cluster: there is only one
copy of pg_group per cluster, not
one per database.
