Removes 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. Refer to DROP AGGREGATE, DROP FUNCTION, and DROP PROCEDURE 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 Greenplum Database 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.
