71 ALTER DEFAULT PRIVILEGES allows you to set the privileges that will be
72 applied to objects created in the future. (It does not affect
73 privileges assigned to already-existing objects.) Currently, only the
74 privileges for schemas, tables (including views and foreign tables),
75 sequences, functions, and types (including domains) can be altered. For
76 this command, functions include aggregates and procedures. The words
77 FUNCTIONS and ROUTINES are equivalent in this command. (ROUTINES is
78 preferred going forward as the standard term for functions and
79 procedures taken together. In earlier PostgreSQL releases, only the
80 word FUNCTIONS was allowed. It is not possible to set default
81 privileges for functions and procedures separately.)
82 You can change default privileges only for objects that will be created
84 by yourself or by roles that you are a member of. The privileges can be
85 set globally (i.e., for all objects created in the current database),
86 or just for objects created in specified schemas. Default privileges
87 that are specified per-schema are added to whatever the global default
88 privileges are for the particular object type.
89 As explained under GRANT(7), the default privileges for any object type
91 normally grant all grantable permissions to the object owner, and may
92 grant some privileges to PUBLIC as well. However, this behavior can be
93 changed by altering the global default privileges with ALTER DEFAULT
94 PRIVILEGES.
95 Parameters
97 target_role
98 The name of an existing role of which the current role is a member.
99 If FOR ROLE is omitted, the current role is assumed.
100 schema_name
102 The name of an existing schema. If specified, the default
103 privileges are altered for objects later created in that schema. If
104 IN SCHEMA is omitted, the global default privileges are altered.
105 IN SCHEMA is not allowed when using ON SCHEMAS as schemas can't be
106 nested.
107 role_name
109 The name of an existing role to grant or revoke privileges for.
110 This parameter, and all the other parameters in
111 abbreviated_grant_or_revoke, act as described under GRANT(7) or
112 REVOKE(7), except that one is setting permissions for a whole class
113 of objects rather than specific named objects.
114
116 Use psql(1)'s \ddp command to obtain information about existing
117 assignments of default privileges. The meaning of the privilege values
118 is the same as explained for \dp under GRANT(7).
119 If you wish to drop a role for which the default privileges have been
121 altered, it is necessary to reverse the changes in its default
122 privileges or use DROP OWNED BY to get rid of the default privileges
123 entry for the role.
124
126 Grant SELECT privilege to everyone for all tables (and views) you
127 subsequently create in schema myschema, and allow role webuser to
128 INSERT into them too:
129 ALTER DEFAULT PRIVILEGES IN SCHEMA myschema GRANT SELECT ON TABLES TO PUBLIC;
131 ALTER DEFAULT PRIVILEGES IN SCHEMA myschema GRANT INSERT ON TABLES TO webuser;
132 Undo the above, so that subsequently-created tables won't have any more
134 permissions than normal:
135 ALTER DEFAULT PRIVILEGES IN SCHEMA myschema REVOKE SELECT ON TABLES FROM PUBLIC;
137 ALTER DEFAULT PRIVILEGES IN SCHEMA myschema REVOKE INSERT ON TABLES FROM webuser;
138 Remove the public EXECUTE permission that is normally granted on
140 functions, for all functions subsequently created by role admin:
141 ALTER DEFAULT PRIVILEGES FOR ROLE admin REVOKE EXECUTE ON FUNCTIONS FROM PUBLIC;
143
145 There is no ALTER DEFAULT PRIVILEGES statement in the SQL standard.
