Calling a trigger from a trigger

От

Дата:
I have a number of tables that have a group of fields in common.
I want to process theses fields in a before trigger (before insert or 
update), but each of the tables have before triggers for processing of 
other non-common data fields.

It seems that from a pl/pgsql trigger I cannot call another trigger (the 
one that would be common to all) and if I just attach the common trigger as 
a second trigger to each table then (according to the docs) there is no 
guarantee of the execution order (which I need ... each table requires the 
common stuff to be processed before the non-common stuff).

Is there a way to achieve this requirement without duplicating the code 
from the common-part in each of table triggers?

Thanks, in advance, for any thoughts
Mike.
