ha, thanks, my machine is plenty strong, fit and hale, new 16 CPU/64GB RDS instance... I was just curious if there were any performance options to change during a restore for any gains. Seems like good reasons to avoid disabling autovacuum, though.

If your machine is too weak to handle the combined workload of restore +
autovacuum, that might get you something. Otherwise, you are just cheating:
the restore might be faster, but the database is not usable before autovacuum
and autoanalyze have proessed all restored tables.
I wouldn't recommend turning autovacuum off, because it is a dangerous thing
to do. If you forget to enable it, your database will be in big trouble.
