It's probably easier than you think. Briefly, it goes like this:
1) read
http://www.postgresql.org/docs/current/static/tutorial-inheritance.html
2) try those examples
3) In your case:

create table bob_def (surname text);
create table bob () inherits (bob_def);
create table bob_test () inherits (bob_def);

insert into bob (surname) values ('smith');
insert into bob_test (surname) values ('gazpacho');

\d bob
\d bob_test
alter table bob_def add column age integer;
\d bob
\d bob_test

update bob set age=104 where surname='smith';

select * from bob;

Note:
You'll need to index the subtables separately if that's important to
you.
