The are all identical:

itvtrackdata=> select datname,age(datfrozenxid),age(datvacuumxid) from
pg_database;
     datname      |    age    |    age    
------------------+-----------+-----------
 postgres         | 295995059 | 295995059
 itvtrackdata     | 295995059 | 295995059
 itvtrackdatauser | 295995059 | 295995059
 itvtrackdatapos  | 295995059 | 295995059
 template1        | 295995059 | 295995059
 template0        | 295995059 | 295995059
(6 rows)

itvtrackdata=>
