+.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))
