Hi,

as far as I understood the thing, take OIDs as 'internal' (they are
unique all over all databases) and do not use them to organize your
data.

Something like

  CREATE TABLE park (
    id serial primary key,
    region int4 references region,
    ...
  );

  CREATE TABLE region (
    id serial primary key,
    ...
  ) ;

should work.

Is SERIAL still INT4 in v7.2?
