.SH "NAME"
DROP_EXTENSION \- remove an extension
.SH "SYNOPSIS"
.sp
.nf
DROP EXTENSION [ IF EXISTS ] \fIname\fR [, \&.\&.\&.] [ CASCADE | RESTRICT ]
.fi
.SH "DESCRIPTION"
.PP
\fBDROP EXTENSION\fR
removes extensions from the database\&. Dropping an extension causes its member objects, and other explicitly dependent routines (see
ALTER ROUTINE (\fBALTER_ROUTINE\fR(7)), the
DEPENDS ON EXTENSION \fIextension_name\fR
action), to be dropped as well\&.
.PP
You must own the extension to use
\fBDROP EXTENSION\fR\&.
.SH "PARAMETERS"
.PP
IF EXISTS
.RS 4
Do not throw an error if the extension does not exist\&. A notice is issued in this case\&.
.RE
.PP
\fIname\fR
.RS 4
The name of an installed extension\&.
.RE
.PP
CASCADE
.RS 4
Automatically drop objects that depend on the extension, and in turn all objects that depend on those objects (see
Section\ \&5.14)\&.
.RE
.PP
RESTRICT
.RS 4
This option prevents the specified extensions from being dropped if other objects, besides these extensions, their members, and their explicitly dependent routines, depend on them\&.\ \& This is the default\&.
.RE
.SH "EXAMPLES"
.PP
To remove the extension
hstore
from the current database:
.sp
.if n \{\
.RS 4
.\}
.nf
DROP EXTENSION hstore;
.fi
.if n \{\
.RE
.\}
.sp
This command will fail if any of
hstore\*(Aqs objects are in use in the database, for example if any tables have columns of the
hstore
type\&. Add the
CASCADE
option to forcibly remove those dependent objects as well\&.
.SH "COMPATIBILITY"
.PP
\fBDROP EXTENSION\fR
is a
PostgreSQL
extension\&.
.SH "SEE ALSO"
CREATE EXTENSION (\fBCREATE_EXTENSION\fR(7)), ALTER EXTENSION (\fBALTER_EXTENSION\fR(7))
