Temporary tables also are not autovacuumed.
And that's pretty much the most of the differences.

Thanks. So, the Write-Ahead-Logging (being used or not) does not matter?

And, is there anything like RAM-only tables? I really don't care whether the staging data is lost on the rare event of a machine crash, or whether the query crashes due to lack of memory (I make sure there's enough w/o paging) - I only care about performance here.
