DESCRIPTION

40       ALTER EXTENSION changes the definition of an installed extension. There
41       are several subforms:
42
43       UPDATE
44           This form updates the extension to a newer version. The extension
45           must supply a suitable update script (or series of scripts) that
46           can modify the currently-installed version into the requested
47           version.
48
49       SET SCHEMA
50           This form moves the extension's objects into another schema. The
51           extension has to be relocatable for this command to succeed.
52
53       ADD member_object
54           This form adds an existing object to the extension. This is mainly
55           useful in extension update scripts. The object will subsequently be
56           treated as a member of the extension; notably, it can only be
57           dropped by dropping the extension.
58
59       DROP member_object
60           This form removes a member object from the extension. This is
61           mainly useful in extension update scripts. The object is not
62           dropped, only disassociated from the extension.
63       See Section 35.15, “Packaging Related Objects into an Extension”, in
64       the documentation for more information about these operations.
65
66       You must own the extension to use ALTER EXTENSION. The ADD/DROP forms
67       require ownership of the added/dropped object as well.

PARAMETERS

70       name
71           The name of an installed extension.
72
73       new_version
74           The desired new version of the extension. This can be written as
75           either an identifier or a string literal. If not specified, ALTER
76           EXTENSION UPDATE attempts to update to whatever is shown as the
77           default version in the extension's control file.
78
79       new_schema
80           The new schema for the extension.
81
82       object_name, agg_name, function_name, operator_name
83           The name of an object to be added to or removed from the extension.
84           Names of tables, aggregates, domains, foreign tables, functions,
85           operators, operator classes, operator families, sequences, text
86           search objects, types, and views can be schema-qualified.
87
88       agg_type
89           An input data type on which the aggregate function operates. To
90           reference a zero-argument aggregate function, write * in place of
91           the list of input data types.
92
93       source_type
94           The name of the source data type of the cast.
95
96       target_type
97           The name of the target data type of the cast.
98
99       argmode
100           The mode of a function argument: IN, OUT, INOUT, or VARIADIC. If
101           omitted, the default is IN. Note that ALTER EXTENSION does not
102           actually pay any attention to OUT arguments, since only the input
103           arguments are needed to determine the function's identity. So it is
104           sufficient to list the IN, INOUT, and VARIADIC arguments.
105
106       argname
107           The name of a function argument. Note that ALTER EXTENSION does not
108           actually pay any attention to argument names, since only the
109           argument data types are needed to determine the function's
110           identity.
111
112       argtype
113           The data type(s) of the function's arguments (optionally
114           schema-qualified), if any.
115
116       left_type, right_type
117           The data type(s) of the operator's arguments (optionally
118           schema-qualified). Write NONE for the missing argument of a prefix
119           or postfix operator.
120
121       PROCEDURAL
122           This is a noise word.
123

EXAMPLES

125       To update the hstore extension to version 2.0:
126
127           ALTER EXTENSION hstore UPDATE TO '2.0';
128
129       To change the schema of the hstore extension to utils:
130
131           ALTER EXTENSION hstore SET SCHEMA utils;
132
133       To add an existing function to the hstore extension:
134
135           ALTER EXTENSION hstore ADD FUNCTION populate_record(anyelement, hstore);
