Perhaps going even further, ANALYZE could have a quick-and-dirty mode,
where it just analyzes say 10 random pages per table and fills in as
much data as it can from that. And then it does the real analyze. (Or
it could even insert fake statistics to trigger autoanalyze.) That way,
you could have a database back in business in less than a minute.
