Only thing I can think of is if storage method had been changed. Not
sure if that would even affect it, or if it could do that by itself.

'full' is an option to vacuum, essentially, as is 'analyze', so there
are four variants (ignoring the freeze option):
vacuum
vacuum analyze
vacuum full

It's all pretty obvious from

Perhaps the other machine has a filesystem limit forbidding such large

table1 NATURAL INNER JOIN table2, for example, is equivalent to table1

Then do *nothing* until you have dumped the db to a file, and cleanly
resotred from it. You should also manually check for inconsistencies,
although if you have correctly used contraints it should barf on input
if there are any. Assuming your DB is fully normalised.

All trying to access the same row seems a bad idea generally. Instead,
why not make it store a new record for each instance, and have a cronjob
each day update the statist
rsync logs together using postgres. Works like a charm. You do have
to allow that queries are going to take a long time. I use about 6
queries to summarise a quarter's data - each run for each month, so a
total of 18 queries. These run in a little over 24 hours. And there are
many, many recor
an days I would expect.
However, you may want to ensure that all tuning in postgresql.conf is
correct, as it may not be using all possible resources. That will
probably only make a small difference.
