debugging triggers - get original statement? - Mailing list pgsql-sql

Hi
I have a situation where a summary table is updated via triggers on multiple
tables.
E.g. an insert is done on table1; a trigger (trigger_func_1) then causes an
update on table2 , which in turn update table3 using another trigger
(trigger_func_2).

I'm encountering invalid data on table3 and I suspect a bug in
trigger_func_2.

I now want to add debugging to trigger_func_2 where I log the original
statement (transaction?).
I.e. I'm interested in something like "INSERT INTO table1.... " 
Anybody have any ideas on how I can get this original statement ?

Thanks 
GMB
