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.
