Order of triggers

["Didier Gasser-Morlay" <didiergm(at)gmail(dot)com>]

Hi,

In my database, I am creating several triggers, some tables have more
than one trigger for the same Fire/Event (ie BEFORE INSERT)
combination.

How can I know in which order the triggers will fire or how can I
force a specific order to be used ?

In firebird, I used to use a "Position" parameter to determine the
order, is there an equivalent in PostgreSQL ?

Thanks for your help
