Each database has its own pg_class:

SELECT relname, relkind, relisshared
FROM pg_class
WHERE relname = 'pg_class';

 relname  | relkind | relisshared
----------+---------+-------------
 pg_class | r       | f
(1 row)

You can query pg_class to see that its contents are different in
different databases, and you can use "ls -li" on the on-disk files
to see that they have different inode numbers and (usually) different
sizes and modified times.

Here are the shared objects in an 8.0.1 database (excluding indexes):

SELECT relname, relkind
FROM pg_class
WHERE relkind <> 'i' AND relisshared IS TRUE
ORDER BY relname;

    relname    | relkind
---------------+---------
 pg_database   | r
 pg_group      | r
 pg_shadow     | r
 pg_tablespace | r
 pg_toast_1260 | t
 pg_toast_1261 | t
 pg_toast_1262 | t
 pg_xactlock   | s
(8 rows)
