I'm concerned there could still be paths that lead to an error. For
pg_restore, or when loading a SQL file, a single error isn't fatal
(unless -e is specified), but it still could be somewhat scary to see
errors during a reload.

Also, it's new behavior, so it may cause some minor surprises, or there
might be minor interactions to work out. For instance, dumping stats
doesn't make a lot of sense if pg_upgrade (or something else) is just
going to run analyze anyway.

What do you think about starting off with it as non-default, and then
switching it to default in 18?
