	   TO {	[ GROUP	] role_name | PUBLIC } [, ...] [ WITH GRANT OPTION ]

       GRANT { EXECUTE | ALL [ PRIVILEGES ] }

	   TO {	[ GROUP	] role_name | PUBLIC } [, ...] [ WITH GRANT OPTION ]

       REVOKE [	GRANT OPTION FOR ]
	   { { SELECT |	INSERT | UPDATE	| DELETE | TRUNCATE | REFERENCES | TRIGGER }

	   ON FUNCTIONS
	   FROM	{ [ GROUP ] role_name |	PUBLIC } [, ...]
	   [ CASCADE | RESTRICT	]

       REVOKE [	GRANT OPTION FOR ]

	   [ CASCADE | RESTRICT	]

DESCRIPTION
       ALTER DEFAULT PRIVILEGES	allows you to set the privileges that will be
       applied to objects created in the future. (It does not affect
       privileges assigned to already-existing objects.) Currently, only the
       privileges for tables (including	views and foreign tables), sequences,
       functions, and types (including domains)	can be altered.

       You can change default privileges only for objects that will be created
       by yourself or by roles that you	are a member of. The privileges	can be
       set globally (i.e., for all objects created in the current database),
       or just for objects created in specified	schemas. Default privileges
       that are	specified per-schema are added to whatever the global default
       privileges are for the particular object	type.

       As explained under GRANT(7), the	default	privileges for any object type
       normally	grant all grantable permissions	to the object owner, and may
       grant some privileges to	PUBLIC as well.	However, this behavior can be
       changed by altering the global default privileges with ALTER DEFAULT
       PRIVILEGES.

   Parameters
       target_role
	   The name of an existing role	of which the current role is a member.
	   If FOR ROLE is omitted, the current role is assumed.

       schema_name
	   The name of an existing schema. If specified, the default
	   privileges are altered for objects later created in that schema. If
	   IN SCHEMA is	omitted, the global default privileges are altered.

       role_name
	   The name of an existing role	to grant or revoke privileges for.
	   This	parameter, and all the other parameters	in
	   abbreviated_grant_or_revoke,	act as described under GRANT(7)	or
	   REVOKE(7), except that one is setting permissions for a whole class
	   of objects rather than specific named objects.

NOTES
       Use psql(1)'s \ddp command to obtain information	about existing
       assignments of default privileges. The meaning of the privilege values
       is the same as explained	for \dp	under GRANT(7).

       If you wish to drop a role for which the	default	privileges have	been
       altered,	it is necessary	to reverse the changes in its default
       privileges or use DROP OWNED BY to get rid of the default privileges
       entry for the role.

EXAMPLES
       Grant SELECT privilege to everyone for all tables (and views) you
       subsequently create in schema myschema, and allow role webuser to
       INSERT into them	too:

	   ALTER DEFAULT PRIVILEGES IN SCHEMA myschema GRANT SELECT ON TABLES TO PUBLIC;
	   ALTER DEFAULT PRIVILEGES IN SCHEMA myschema GRANT INSERT ON TABLES TO webuser;

       Undo the	above, so that subsequently-created tables won't have any more
       permissions than	normal:

	   ALTER DEFAULT PRIVILEGES IN SCHEMA myschema REVOKE SELECT ON	TABLES FROM PUBLIC;
	   ALTER DEFAULT PRIVILEGES IN SCHEMA myschema REVOKE INSERT ON	TABLES FROM webuser;

       Remove the public EXECUTE permission that is normally granted on
       functions, for all functions subsequently created by role admin:

	   ALTER DEFAULT PRIVILEGES FOR	ROLE admin REVOKE EXECUTE ON FUNCTIONS FROM PUBLIC;

COMPATIBILITY
       There is	no ALTER DEFAULT PRIVILEGES statement in the SQL standard.
