.SH "DESCRIPTION"
.PP
\fBALTER EXTENSION\fR
changes the definition of an installed extension\&. There are several subforms:
.PP
UPDATE
.RS 4
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\&.
.RE
.PP
SET SCHEMA
.RS 4
This form moves the extension\*(Aqs objects into another schema\&. The extension has to be
relocatable
for this command to succeed\&.
.RE
.PP
ADD \fImember_object\fR
.RS 4
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\&.
.RE
.PP
DROP \fImember_object\fR
.RS 4
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\&.
.RE
See
Section 35.15, \(lqPackaging Related Objects into an Extension\(rq, in the documentation
for more information about these operations\&.
.PP
You must own the extension to use
\fBALTER EXTENSION\fR\&. The
ADD/DROP
forms require ownership of the added/dropped object as well\&.
.SH "PARAMETERS"
.PP
.PP
\fIname\fR
.RS 4
The name of an installed extension\&.
.RE
.PP
\fInew_version\fR
.RS 4
The desired new version of the extension\&. This can be written as either an identifier or a string literal\&. If not specified,
\fBALTER EXTENSION UPDATE\fR
attempts to update to whatever is shown as the default version in the extension\*(Aqs control file\&.
.RE
.PP
\fInew_schema\fR
.RS 4
The new schema for the extension\&.
.RE
.PP
\fIobject_name\fR, \fIagg_name\fR, \fIfunction_name\fR, \fIoperator_name\fR
.RS 4
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, sequences, text search objects, types, and views can be schema\-qualified\&.
.RE
.PP
\fIagg_type\fR
.RS 4
An input data type on which the aggregate function operates\&. To reference a zero\-argument aggregate function, write
*
in place of the list of input data types\&.
.RE
.PP
\fIsource_type\fR
.RS 4
The name of the source data type of the cast\&.
.RE
.PP
\fItarget_type\fR
.RS 4
The name of the target data type of the cast\&.
.RE
.PP
\fIargmode\fR
.RS 4
The mode of a function argument:
IN,
OUT,
INOUT, or
VARIADIC\&. If omitted, the default is
IN\&. Note that
\fBALTER EXTENSION\fR
does not actually pay any attention to
OUT
arguments, since only the input arguments are needed to determine the function\*(Aqs identity\&. So it is sufficient to list the
IN,
INOUT, and
VARIADIC
arguments\&.
.RE
.PP
\fIargname\fR
.RS 4
The name of a function argument\&. Note that
\fBALTER EXTENSION\fR
does not actually pay any attention to argument names, since only the argument data types are needed to determine the function\*(Aqs identity\&.
.RE
.PP
\fIargtype\fR
.RS 4
The data type(s) of the function\*(Aqs arguments (optionally schema\-qualified), if any\&.
.RE
.PP
\fIleft_type\fR, \fIright_type\fR
.RS 4
The data type(s) of the operator\*(Aqs arguments (optionally schema\-qualified)\&. Write
NONE
for the missing argument of a prefix or postfix operator\&.
.RE
.PP
PROCEDURAL
.RS 4
This is a noise word\&.
.RE
.SH "EXAMPLES"
.PP
To update the
hstore
extension to version 2\&.0:
.sp
.if n \{\
.RS 4
.\}
.nf
ALTER EXTENSION hstore UPDATE TO \*(Aq2\&.0\*(Aq;
.fi
.if n \{\
.RE
.\}
.PP
To change the schema of the
hstore
extension to
utils:
.sp
.if n \{\
.RS 4
.\}
.nf
ALTER EXTENSION hstore SET SCHEMA utils;
.fi
.if n \{\
.RE
.\}
.PP
To add an existing function to the
hstore
extension:
.sp
.if n \{\
.RS 4
.\}
.nf
ALTER EXTENSION hstore ADD FUNCTION populate_record(anyelement, hstore);
.fi
.if n \{\
.RE
.\}
.SH "COMPATIBILITY"
.PP
\fBALTER EXTENSION\fR
is a
PostgreSQL
extension\&.
.SH "SEE ALSO"
CREATE EXTENSION (\fBCREATE_EXTENSION\fR(7)), DROP EXTENSION (\fBDROP_EXTENSION\fR(7))
