Sr:
I have tried to look at the postgreSQL www and contact some people but
i don't
have full internet just e-mail so it's a little hard to search exactly what
i'm looking for, please help me to find out about this if you can:
1) There are primary keys, foreing keys and not null statements
for postgres?
2) There is possible to emulate this things with the rule system?
3)How can i get a manual about the system rules for postgres?
Regards
Otto
