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));
