"template1"
2008-04-30 12:04:36 EDT LOG: autovacuum: processing database

2008-04-30 12:05:36 EDT LOG: autovacuum: processing database
"template1"
2008-04-30 12:06:36 EDT LOG: autovacuum: processing database
"itvtrackdatapos"

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)
