I've some question about PostgreSQL object-orientations, as explained in the
JDBC prgramming manual (extended Postrgres API).
You can use table A as a type for a field in table B like this : create table
A (foo text); create table B (fee B);
This ensure 1-to-n relation between A and B like classical B foreign
key linked to A primary Key, with relational constraint morevoer : you can't
delete any tuple in A still linked to in B. Am i right to this point ?

Ok, here's what seems to be impossible :
- Declare a field as an array of another table, so as to have a n-to-n
relationship. I've tried create B (fee B[]), it doesn't function.
- Declare a recursive declaration. I tried create table A(foo A), it
doesn't function either.
