DROP [ PROCEDURAL ] LANGUAGE [ IF EXISTS ] \fIname\fR [ CASCADE | RESTRICT ]
.fi

.PP
As of
PostgreSQL
9\&.1, most procedural languages have been made into
\(lqextensions\(rq, and should therefore be removed with
DROP EXTENSION (\fBDROP_EXTENSION\fR(7))
not
\fBDROP LANGUAGE\fR\&.
.sp .5v
.RE
.SH "PARAMETERS"
.PP
IF EXISTS
.RS 4
Do not throw an error if the language does not exist\&. A notice is issued in this case\&.
.RE
.PP
\fIname\fR
.RS 4
The name of an existing procedural language\&. For backward compatibility, the name can be enclosed by single quotes\&.
.RE
.PP
CASCADE
.RS 4
Automatically drop objects that depend on the language (such as functions in the language), and in turn all objects that depend on those objects (see
Section 5.13, \(lqDependency Tracking\(rq, in the documentation)\&.
.RE
.PP
RESTRICT
.RS 4
Refuse to drop the language if any objects depend on it\&. This is the default\&.
.RE
.SH "EXAMPLES"
.PP
This command removes the procedural language
plsample:
.sp
.if n \{\
.RS 4
.\}
.nf
DROP LANGUAGE plsample;
.fi
.if n \{\
.RE
.\}
.SH "COMPATIBILITY"
.PP
There is no
\fBDROP LANGUAGE\fR
statement in the SQL standard\&.
.SH "SEE ALSO"
