Grant Permission to Users

GRANT
    priv_type [, priv_type ] ...
    ON database_table_or_view_name
    TO principal_specification [, principal_specification] ...
    [WITH GRANT OPTION];

Examples:

GRANT SELECT ON table1 TO USER user1;
GRANT SELECT ON DATABASE db1 TO USER user1;
GRANT SELECT ON table1 TO ROLE role1;

Grant on database grants privileges on all tables or views under this database. If a user is granted a privilege WITH GRANT OPTION on a table or view, then the user can also grant/revoke privileges of other users and roles on those objects.

Remove Permission of Users

REVOKE [GRANT OPTION FOR]
    priv_type [, priv_type ] ...
    ON database_table_or_view_name
    FROM principal_specification [, principal_specification] ... ;

principal_specification
: USER user
| ROLE role

priv_type
: SELECT
    UPDATE
    INSERT
    DELETE

Examples:

REVOKE SELECT ON table1 FROM USER user1;
REVOKE SELECT ON DATABASE db1 FROM USER user1;

If a user is granted a privilege WITH GRANT OPTION on a table or view, then the user can also grant/revoke privileges of other users and roles on those objects. The grant option for a privilege can be removed while still keeping the privilege by using REVOKE GRANT OPTION FOR <privilege>.
