RE: FOREIGN KEY

Hi,

Foreign Keys are implemented with triggers and you can list thim all by
doing a 'SELECT * FROM pg_trigger;'. The triggers starting with
RI_ConstraintTrigger_?????? are those in question, but which trigger goes
with which foreign key is not obvious. If you have named the Foriegn keys
then it should not be too much problem. Otherwise you should me able to
make it out from the tgargs field. When you have found out which triggers
you need to drop use DROP TRIGGER ... to remove them.

You can add the Foreign keys again after you have copied all the data with
ALTER TABLE ...

Hope this helps

Ben
