System privileges are automatically granted to the system administrator at installation, and may be passed on to other idents.
Object and access privileges are initially granted only to the creator of an object. The creator may however grant the privileges on to other idents.
All privileges may be granted with or without
GRANT OPTION, which controls the right of the receiving ident to grant the privilege on to another ident.
Certain operations are not controlled by explicit privileges, but may only be performed by the creator of the object involved. These operations include
ALTER(with the exception of
ALTER IDENT, which may be performed by either the ident himself or by the creator of the ident),
COMMENT. Similarly, privileges may only be revoked by their grantor.
