52 ALTER EXTENSION changes the definition of an installed extension. There
53 are several subforms:
54 UPDATE
56 This form updates the extension to a newer version. The extension
57 must supply a suitable update script (or series of scripts) that
58 can modify the currently-installed version into the requested
59 version.
60 SET SCHEMA
62 This form moves the extension's objects into another schema. The
63 extension has to be relocatable for this command to succeed.
64 ADD member_object
66 This form adds an existing object to the extension. This is mainly
67 useful in extension update scripts. The object will subsequently be
68 treated as a member of the extension; notably, it can only be
69 dropped by dropping the extension.
70 DROP member_object
72 This form removes a member object from the extension. This is
73 mainly useful in extension update scripts. The object is not
74 dropped, only disassociated from the extension.
75 See Section 38.17 for more information about these operations.
76 You must own the extension to use ALTER EXTENSION. The ADD/DROP forms
78 require ownership of the added/dropped object as well.
79
81 name
82 The name of an installed extension.
83 new_version
85 The desired new version of the extension. This can be written as
86 either an identifier or a string literal. If not specified, ALTER
87 EXTENSION UPDATE attempts to update to whatever is shown as the
88 default version in the extension's control file.
89 new_schema
91 The new schema for the extension.
92 object_name
94 aggregate_name
95 function_name
96 operator_name
97 procedure_name
98 routine_name
99 The name of an object to be added to or removed from the extension.
100 Names of tables, aggregates, domains, foreign tables, functions,
101 operators, operator classes, operator families, procedures,
102 routines, sequences, text search objects, types, and views can be
103 schema-qualified.
104 source_type
106 The name of the source data type of the cast.
107 target_type
109 The name of the target data type of the cast.
110 argmode
112 The mode of a function, procedure, or aggregate argument: IN, OUT,
113 INOUT, or VARIADIC. If omitted, the default is IN. Note that ALTER
114 EXTENSION does not actually pay any attention to OUT arguments,
115 since only the input arguments are needed to determine the
116 function's identity. So it is sufficient to list the IN, INOUT, and
117 VARIADIC arguments.
118 argname
120 The name of a function, procedure, or aggregate argument. Note that
121 ALTER EXTENSION does not actually pay any attention to argument
122 names, since only the argument data types are needed to determine
123 the function's identity.
124 argtype
126 The data type of a function, procedure, or aggregate argument.
127 left_type
129 right_type
130 The data type(s) of the operator's arguments (optionally
131 schema-qualified). Write NONE for the missing argument of a prefix
132 operator.
133 PROCEDURAL
135 This is a noise word.
136 type_name
138 The name of the data type of the transform.
139 lang_name
141 The name of the language of the transform.
142
144 To update the hstore extension to version 2.0:
145 ALTER EXTENSION hstore UPDATE TO '2.0';
147 To change the schema of the hstore extension to utils:
149 ALTER EXTENSION hstore SET SCHEMA utils;
151 To add an existing function to the hstore extension:
153 ALTER EXTENSION hstore ADD FUNCTION populate_record(anyelement, hstore);
155
157 ALTER EXTENSION is a PostgreSQL extension.
