Functions

alter_routine_attributes

Apply the actions of ALTER FUNCTION to the routine AlterFunction found and whose ownership it checked, in its order: the actions in written order, which a procedure may not use for its function-only attributes and none may repeat; LEAKPROOF, which needs a superuser; COST; ROWS, positive and only for a set-returning routine; the SUPPORT function; and PARALLEL. The SET actions are left for the caller to apply last.
