+.SH "NAME"
+DROP_OPERATOR_FAMILY \- remove an operator family
+.SH "SYNOPSIS"
+.sp
+.nf
+DROP OPERATOR FAMILY [ IF EXISTS ] \fIname\fR USING \fIindex_method\fR [ CASCADE | RESTRICT ]
+.fi
+.SH "DESCRIPTION"
+.PP
+\fBDROP OPERATOR FAMILY\fR
+drops an existing operator family\&. To execute this command you must be the owner of the operator family\&.
+.PP
+\fBDROP OPERATOR FAMILY\fR
+includes dropping any operator classes contained in the family, but it does not drop any of the operators or functions referenced by the family\&. If there are any indexes depending on operator classes within the family, you will need to specify
+CASCADE
+for the drop to complete\&.
+.SH "PARAMETERS"
+.PP
+IF EXISTS
+.RS 4
+Do not throw an error if the operator family does not exist\&. A notice is issued in this case\&.
+.RE
+.PP
+\fIname\fR
+.RS 4
+The name (optionally schema\-qualified) of an existing operator family\&.
+.RE
+.PP
+\fIindex_method\fR
+.RS 4
+The name of the index access method the operator family is for\&.
+.RE
+.PP
+CASCADE
+.RS 4
+Automatically drop objects that depend on the operator family, and in turn all objects that depend on those objects (see
+Section\ \&5.14)\&.
+.RE
+.PP
+RESTRICT
+.RS 4
+Refuse to drop the operator family if any objects depend on it\&. This is the default\&.
+.RE
+.SH "EXAMPLES"
+.PP
+Remove the B\-tree operator family
+float_ops:
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+DROP OPERATOR FAMILY float_ops USING btree;
+.fi
+.if n \{\
+.RE
+.\}
+.sp
+This command will not succeed if there are any existing indexes that use operator classes within the family\&. Add
+CASCADE
+to drop such indexes along with the operator family\&.
+.SH "COMPATIBILITY"
+.PP
+There is no
+\fBDROP OPERATOR FAMILY\fR
+statement in the SQL standard\&.
