+.fi

+.if n \{\
+.RE
+.\}
+.SH "COMPATIBILITY"
+.PP
+This command conforms to ISO/IEC 9075\-9 (SQL/MED), except that the standard only allows one foreign table to be dropped per command, and apart from the
+IF EXISTS
+option, which is a
+PostgreSQL
+extension\&.
+.SH "SEE ALSO"
+ALTER FOREIGN TABLE (\fBALTER_FOREIGN_TABLE\fR(7)), CREATE FOREIGN TABLE (\fBCREATE_FOREIGN_TABLE\fR(7))
