From what I understand they are occurring because the machine is to busy
doing the restore to get to the autovacuum task in a timely manner. So I
would say ignore and check back later to see that the autovacuum is working.
Given that it is ANALYZE that is being cancelled I would run a manual
ANALYZE after the restore is done to update the database statistics.
The machine is a development server and no one was working on it (today
is Saturday) apart of me. It has 4 modern and fast CPU,
Running ANALYZE VERBOSE does not give any unusual output. Only for each
table lines like:
I would not expect that it would. The purpose for running it was to make
sure the statistics for the tables in the database where up to date.

How could I check that the autovacuum is working?
Two ways:
1) Look in the logs for autovacuum lines.
2) Query the pg_stat_all_tables view.
