Where should I see it? The output of "ps ax | grep auto" is empty. Does 
it mean that auto vacuum is not running? How can I check if there is a 
problem?

Oh, then do you have any idea what caused this? E.g. a postgres client 
seeing an older version of the data? "Older" means that the postgres 
client was started today and it saw the data from 2 days ago, then 
suddenly it started to see the fresh data.

Thanks,
