Postgres SQL

[Peter Mikula]

Caff,

  ako sa daju v Postgres zviazat kluce v tabulkach, kedze 
  PSQL nepodporuje REFERENCES a FOREIGN KEY a teda nasledovny priklad
  nefunguje ?

   CREATE TABLE a (
     uid INTEGER CONSTRAINT a_pk PRIMARY KEY,
     address VARCHAR NOT NULL
   ); 
   
   CREATE TABLE b (
     uid INTEGER CONSTRAINT b_fk REFERENCES a(uid),
     name VARCHAR NOT NULL 
   );
