No, I make a small test :
In _PG_fini I create a file and close it (via fopen), I quit pgsql and
the file are never created, bul a small lsof say me that the module are
unloaded.

How can I detect (in language C) that the trigger work on a transaction
context or a row context ?
And it is possible to receive an event when this transaction are ended ?
