Schema diff tools excludes the SET directive from the function header

Hi
Schema diff utilities exclude the SET directive from the function header in
compare mode.
Reproducing the problem:
1. Create a copy of the database with the function containing the SET
directive
2. Modify the function and perform the comparison.
In the resulting script, I am missing the SET directive in the function:

CREATE OR REPLACE FUNCTION bpd.class_del(
iid bigint)
RETURNS void
LANGUAGE 'plpgsql'
COST 100
VOLATILE SECURITY DEFINER PARALLEL UNSAFE
<--SET search_path=bpd, err-->
AS $BODY$
