## NAME
       DROP_FOREIGN_DATA_WRAPPER - remove a foreign-data wrapper

## SYNOPSIS
       DROP FOREIGN DATA WRAPPER [ IF EXISTS ] _name_ [, ...] [ CASCADE | RESTRICT ]

## DESCRIPTION
       **DROP** **FOREIGN** **DATA** **WRAPPER** removes an existing foreign-data wrapper. To execute this command,
       the current user must be the owner of the foreign-data wrapper.

## PARAMETERS
       IF EXISTS
           Do not throw an error if the foreign-data wrapper does not exist. A notice is issued in
           this case.

       _name_
           The name of an existing foreign-data wrapper.

       CASCADE
           Automatically drop objects that depend on the foreign-data wrapper (such as foreign
           tables and servers), and in turn all objects that depend on those objects (see
           Section 5.14).

       RESTRICT
           Refuse to drop the foreign-data wrapper if any objects depend on it. This is the default.

## EXAMPLES

           DROP FOREIGN DATA WRAPPER dbi;

## COMPATIBILITY
       **DROP** **FOREIGN** **DATA** **WRAPPER** conforms to ISO/IEC 9075-9 (SQL/MED). The IF EXISTS clause is a
       PostgreSQL extension.
