Ahhh okay, I didnt know how to extract the age for a database. Learnt
something new here.

My *_freeze_* values are:
autovacuum_freeze_max_age = 200000000
#vacuum_freeze_min_age = 100000000
The vacuum_freeze_min_age is the default at 100 million (I assume).
How much is the age decremented by on a vacuum run then?
