DESCRIPTION

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
83       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
90       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
96   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
101       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
108       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

NOTES

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
120       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

EXAMPLES

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
130           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
133       Undo the above, so that subsequently-created tables won't have any more
134       permissions than normal:
135
136           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
139       Remove the public EXECUTE permission that is normally granted on
140       functions, for all functions subsequently created by role admin:
141
142           ALTER DEFAULT PRIVILEGES FOR ROLE admin REVOKE EXECUTE ON FUNCTIONS FROM PUBLIC;
143

COMPATIBILITY

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