Hello guys!

I have found a example in Oracle and I am trying to do it in Postgre. 

Lets say that we have 2 tables.  
Create Table "table1" Of "type1"
Create Table "table2" Of "type2"

I want to refer the first table in the second. I want to reference the whole
table not only one field, so something like that:

CREATE TYPE type2 AS OBJECT (
  var1   NUMBER,
  var2    REF type1
  )

CREATE TABLE table2 OF type2 (  
   PRIMARY KEY (Pk),                                       
   FOREIGN KEY (fk) REFERENCES table1) 

Can i do something like this in Postgre?

Thank you in advance!
George Ant
