.sp
.nf
DROP CONVERSION [ IF EXISTS ] \fIname\fR [ CASCADE | RESTRICT ]
.fi
.SH "DESCRIPTION"
.PP
\fBDROP CONVERSION\fR

\fIname\fR
.RS 4
The name of the conversion\&. The conversion name can be schema\-qualified\&.
.RE
.PP
CASCADE, RESTRICT

To drop the conversion named
myname:
.sp
.if n \{\
.RS 4
.\}
.nf
DROP CONVERSION myname;
.fi
.if n \{\
.RE
.\}
.SH "COMPATIBILITY"
.PP
There is no
\fBDROP CONVERSION\fR
statement in the SQL standard, but a
\fBDROP TRANSLATION\fR
statement that goes along with the
\fBCREATE TRANSLATION\fR
statement that is similar to the
\fBCREATE CONVERSION\fR
statement in PostgreSQL\&.
.SH "SEE ALSO"
ALTER CONVERSION (\fBALTER_CONVERSION\fR(7)), CREATE CONVERSION (\fBCREATE_CONVERSION\fR(7))
