Setting global vars for use with triggers - Mailing list pgsql-general

I'd like to create a trigger which deletes associated
files whenever their corresponding row is deleted.
Problem is, I don't want to hard-code directory
locations in the trigger function. Is there a way to
set a DOCUMENT_ROOT-like variable in Postgresql which
triggers could access and use? I'm using PHP for the
trigger (and PG 8.x).

Thanks,
CSN

PS - Scott and I have been tossing around a few other
ideas here:
