Re: foreign key question: the backend end the connection

Have you renamed any tables used in the foreign keys
(or dumped and restored with different names or some
missing tables).  Under 7.0.2 and earlier there is
a problem with postgres crashing if a constraint trigger
has bad values (due to renames or incomplete restores).
This should be fixed for 7.1 with a message that it's
unable to find the tablename.  I believe that if you
look through the archives (I forget which list though),
you will find a patch for 7.0.2 that will turn the
crash into an exception message with more information.
