         EVENT TRIGGER object_name |
         FOREIGN DATA WRAPPER object_name |
         FOREIGN TABLE object_name |
         FUNCTION function_name [ ( [ [ argmode ] [ argname ] argtype [, ...] ] ) ] |
         MATERIALIZED VIEW object_name |
         OPERATOR operator_name (left_type, right_type) |
         OPERATOR CLASS object_name USING index_method |
         OPERATOR FAMILY object_name USING index_method |
         [ PROCEDURAL ] LANGUAGE object_name |
         PROCEDURE procedure_name [ ( [ [ argmode ] [ argname ] argtype [, ...] ] ) ] |
         ROUTINE routine_name [ ( [ [ argmode ] [ argname ] argtype [, ...] ] ) ] |
         SCHEMA object_name |
         SEQUENCE object_name |
         SERVER object_name |
         TABLE object_name |
         TEXT SEARCH CONFIGURATION object_name |
         TEXT SEARCH DICTIONARY object_name |
         TEXT SEARCH PARSER object_name |
         TEXT SEARCH TEMPLATE object_name |
         TRANSFORM FOR type_name LANGUAGE lang_name |
         TYPE object_name |
         VIEW object_name

       and aggregate_signature is:

       * |
       [ argmode ] [ argname ] argtype [ , ... ] |
       [ [ argmode ] [ argname ] argtype [ , ... ] ] ORDER BY [ argmode ] [ argname ] argtype [ , ... ]

DESCRIPTION
       ALTER EXTENSION changes the definition of an installed extension. There are several
       subforms:

       UPDATE
           This form updates the extension to a newer version. The extension must supply a
           suitable update script (or series of scripts) that can modify the currently-installed
           version into the requested version.

       SET SCHEMA
           This form moves the extension's objects into another schema. The extension has to be
           relocatable for this command to succeed.

       ADD member_object
           This form adds an existing object to the extension. This is mainly useful in extension
           update scripts. The object will subsequently be treated as a member of the extension;
           notably, it can only be dropped by dropping the extension.

       DROP member_object
           This form removes a member object from the extension. This is mainly useful in
           extension update scripts. The object is not dropped, only disassociated from the
           extension.
       See Section 37.17 for more information about these operations.

       You must own the extension to use ALTER EXTENSION. The ADD/DROP forms require ownership of
       the added/dropped object as well.

PARAMETERS
       name
           The name of an installed extension.

       new_version
           The desired new version of the extension. This can be written as either an identifier
           or a string literal. If not specified, ALTER EXTENSION UPDATE attempts to update to
           whatever is shown as the default version in the extension's control file.

       new_schema
           The new schema for the extension.

       object_name
       aggregate_name
       function_name
       operator_name
       procedure_name
       routine_name
           The name of an object to be added to or removed from the extension. Names of tables,
           aggregates, domains, foreign tables, functions, operators, operator classes, operator
           families, procedures, routines, sequences, text search objects, types, and views can
           be schema-qualified.

       source_type
           The name of the source data type of the cast.

       target_type
           The name of the target data type of the cast.

       argmode
           The mode of a function, procedure, or aggregate argument: IN, OUT, INOUT, or VARIADIC.
           If omitted, the default is IN. Note that ALTER EXTENSION does not actually pay any
           attention to OUT arguments, since only the input arguments are needed to determine the
           function's identity. So it is sufficient to list the IN, INOUT, and VARIADIC
           arguments.

       argname
           The name of a function, procedure, or aggregate argument. Note that ALTER EXTENSION
           does not actually pay any attention to argument names, since only the argument data
           types are needed to determine the function's identity.

       argtype
           The data type of a function, procedure, or aggregate argument.

       left_type
       right_type
           The data type(s) of the operator's arguments (optionally schema-qualified). Write NONE
           for the missing argument of a prefix or postfix operator.

       PROCEDURAL
           This is a noise word.

       type_name
           The name of the data type of the transform.

       lang_name
           The name of the language of the transform.

EXAMPLES
       To update the hstore extension to version 2.0:

           ALTER EXTENSION hstore UPDATE TO '2.0';

       To change the schema of the hstore extension to utils:

           ALTER EXTENSION hstore SET SCHEMA utils;

       To add an existing function to the hstore extension:

           ALTER EXTENSION hstore ADD FUNCTION populate_record(anyelement, hstore);

COMPATIBILITY
       ALTER EXTENSION is a PostgreSQL extension.
