Hi all,

Can any one please let me know the alternative of
"foreign key" referential integrity.  I'v pg 6.5.2
under Linux.  I'm not able to use the foreign key
reference.  when I say "create table emp (id int, dno
int foreign key references dept(dno));

the error message points to "foreign" key.  Can any
one help me in this solving theis problem.






=====
Thanks.
Soundar.

Foreign keys are fully implemented yet.  You can implement them with a
trigger and the loadable procedure under the contrib directory in the
source distribution.  I believe it is under the spi directory there.
