Can anyone tell me where the ON DELETE <action> and ON
UPDATE <action> rules for foreign keys are stored in
the system tables. I would have expected to find them
in one of the relevent pg_trigger entries (ie. one
with a tgtype of 9, 17 or 21). However there is no
difference in these entries regardless of the value of
<action>. I have also scoured other system tables to
no avail.
