Description: pg_dump function dependencies
Details:

I have many many instances of these two problems in pg_dump's output:

1) function code don't seem to be taken into account for dependencies

for example, one function was dumped as follows (note the %TYPE use), but
the general_permissions table was dumped much later:

CREATE FUNCTION all_users_permission_id(character varying, integer,
character varying) RETURNS integer
AS $_$
DECLARE
v_permission_type alias for $1;
v_on_what_id alias for $2;
v_on_which_table alias for $3;
v_permission_id general_permissions.permission_id%TYPE;

non-%TYPE uses get ignored too; e.g. a function containing this line, before
the minions_power_v view was created:

ttt := ttt +
max(0, coalesce(
(0.661 * (select sum(w.value) from weapons_v w where w.party_id = $1
and w.minion_id is not null)
- (select sum(tp_total) from minions_power_v m where m.party_id =
$1))::int
, 0));
