USAGE privileges granted on various kinds of objects to a currently enabled role or by a currently enabled role. In PostgreSQL, this currently applies to collations, domains, foreign-data wrappers, foreign servers, and sequences. There is one row for each combination of object, grantor, and grantee.
Since collations do not have real privileges in PostgreSQL, this view shows implicit non-grantable
USAGE privileges granted by the owner to
PUBLIC for all collations. The other object types, however, show real privileges.
In PostgreSQL, sequences also support
UPDATE privileges in addition to the
USAGE privilege. These are nonstandard and therefore not visible in the information schema.
Name of the role that granted the privilege
Name of the role that the privilege was granted to
Name of the database containing the object (always the current database)
Name of the schema containing the object, if applicable, else an empty string
Name of the object
