NAME

       DROP_ROUTINE - remove a routine

SYNOPSIS

       DROP ROUTINE [ IF EXISTS ] name [ ( [ [ argmode ] [ argname ] argtype [, ...] ] ) ] [, ...]
           [ CASCADE | RESTRICT ]

DESCRIPTION

       DROP ROUTINE removes the definition of an existing routine, which can be an aggregate
       function, a normal function, or a procedure. See under DROP AGGREGATE (DROP_AGGREGATE(7)),
       DROP FUNCTION (DROP_FUNCTION(7)), and DROP PROCEDURE (DROP_PROCEDURE(7)) for the
       description of the parameters, more examples, and further details.

EXAMPLES

       To drop the routine foo for type integer:

           DROP ROUTINE foo(integer);

       This command will work independent of whether foo is an aggregate, function, or procedure.

COMPATIBILITY

       This command conforms to the SQL standard, with these PostgreSQL extensions:

       •   The standard only allows one routine to be dropped per command.

       •   The IF EXISTS option

       •   The ability to specify argument modes and names

       •   Aggregate functions are an extension.

SEE ALSO

       DROP AGGREGATE (DROP_AGGREGATE(7)), DROP FUNCTION (DROP_FUNCTION(7)), DROP PROCEDURE
       (DROP_PROCEDURE(7)), ALTER ROUTINE (ALTER_ROUTINE(7))

       Note that there is no CREATE ROUTINE command.
