NAME
       ALTER_ROUTINE - change the definition of	a routine

SYNOPSIS
       ALTER ROUTINE name [ ( [	[ argmode ] [ argname ]	argtype	[, ...]	] ) ]
	   action [ ...	] [ RESTRICT ]
       ALTER ROUTINE name [ ( [	[ argmode ] [ argname ]	argtype	[, ...]	] ) ]

       ALTER ROUTINE name [ ( [	[ argmode ] [ argname ]	argtype	[, ...]	] ) ]
	   SET SCHEMA new_schema
       ALTER ROUTINE name [ ( [	[ argmode ] [ argname ]	argtype	[, ...]	] ) ]
	   DEPENDS ON EXTENSION	extension_name

       where action is one of:

	   IMMUTABLE | STABLE |	VOLATILE | [ NOT ] LEAKPROOF
	   [ EXTERNAL ]	SECURITY INVOKER | [ EXTERNAL ]	SECURITY DEFINER
	   PARALLEL { UNSAFE | RESTRICTED | SAFE }
	   COST	execution_cost
	   ROWS	result_rows
	   SET configuration_parameter { TO | =	} { value | DEFAULT }
	   SET configuration_parameter FROM CURRENT
	   RESET configuration_parameter
	   RESET ALL

DESCRIPTION
       ALTER ROUTINE changes the definition of a routine, which	can be an
       aggregate function, a normal function, or a procedure. See under	ALTER
       AGGREGATE (ALTER_AGGREGATE(7)), ALTER FUNCTION (ALTER_FUNCTION(7)), and
       ALTER PROCEDURE (ALTER_PROCEDURE(7)) for	the description	of the
       parameters, more	examples, and further details.

EXAMPLES
       To rename the routine foo for type integer to foobar:

	   ALTER ROUTINE foo(integer) RENAME TO	foobar;

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

COMPATIBILITY
       This statement is partially compatible with the ALTER ROUTINE statement
       in the SQL standard. See	under ALTER FUNCTION (ALTER_FUNCTION(7)) and
       ALTER PROCEDURE (ALTER_PROCEDURE(7)) for	more details. Allowing routine
       names to	refer to aggregate functions is	a PostgreSQL extension.

SEE ALSO
       ALTER AGGREGATE (ALTER_AGGREGATE(7)), ALTER FUNCTION
       (ALTER_FUNCTION(7)), ALTER PROCEDURE (ALTER_PROCEDURE(7)), DROP ROUTINE
       (DROP_ROUTINE(7))

       Note that there is no CREATE ROUTINE command.
