The vacuum output shows 91902 live tuples during the first vacuum,
and 91906 during the second. What is the basis of your assertion
that you've lost data?
It does appear that some other operation updated most of the rows in
the table in between, since the second vacuum found 82457 dead tuples.
I'm suspecting that your real problem is an ill-considered update.
