<title>Description</title>
<para>
<command>GRANT</command> allows the creator of an object to give specific permissions to
all users (PUBLIC) or to a certain user or group.
Users other than the creator don't have any access permission
unless the creator GRANTs permissions, after the object
is created.
The <command>GRANT</command> command gives specific permissions on
an object (table, view, sequence) to a user or a group of users.
The special key word <literal>PUBLIC</literal> indicates that the
privileges are to be granted to all users, including those that may
be created later.
</para>
<para>
Once a user has a privilege on an object, he is enabled to exercise
that privilege.
There is no need to GRANT privileges to the creator of
an object, the creator automatically holds ALL privileges, and can
also drop the object.
Users other than the creator do not have any access privileges
unless the creator grants permissions, after the object is created.
There is no need to grant privileges to the creator of an object,
as the creator automatically holds all privileges, and can also
drop the object.
