Yeah. This could use comments from a few more people, but I really
hope we don't ship the final release this way. We do have a "Enable
statistics in pg_dump by default" item in the open items list under
"Decisions to Recheck Mid-Beta", but that's arguably now. It also sort
of looks like we might have a consensus anyway: Jeff said "I lean
towards making it opt-in for pg_dump and opt-out for pg_upgrade" and I
agree with that and it seems you do, too. So perhaps Jeff should make
it so?
