No.
When I sort the triggers I get:

test=# create table trg_str(fld_1 varchar);
CREATE TABLE
test=# insert into trg_str values ('trigger_1_update_fts'),
('trigger_2'), ('trigger_3'), ('trigger_1_check_nocycle');
INSERT 0 4
test=# select * from trg_test order by fld_1 ;
  id | fld_1
----+-------
(0 rows)

test=# select * from trg_str order by fld_1 ;
           fld_1
-------------------------
  trigger_1_check_nocycle
  trigger_1_update_fts
  trigger_2
  trigger_3

Is this how you want them to fire as it does not match what you say above?:
 
(I know they were not declared in that order, but..)
Yes, all "trigger_1_*" are the "actuall triggers triggering the logic", trigger_2 and trigger_3 are only there as part of the "make constraint-triggers fire only once"-mechanism, in which the function in the first trigger is the function performing the actual logic.
So, being I want 2 "logical chunks" to happen I have two "trigger_1"-triggers (there is no established terminilogy for this AFAIK), each calling a function performing the logick which is to happen only once (per row).
 
 
"The first "main" trigger-function is update_company_fts_tf() ... The
second "main" trigger-function is company_parent_no_cycle()"

It might be easier to understand if sketch out a schematic version of
what you are trying to achieve.
 
The point is; I want to functions to be called
 
- update_company_fts_tf()
- company_parent_no_cycle()
 
, each only once, as constraint-triggers on the same table. So they are called by the "level 1 triggers" which must fire first.
 
Is it clearer now what I'm trying to achieve?
