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.
