And here is yet another new version of the full patch set.  I'm planning to
commit 0001 (the new pg_upgrade transfer mode test) tomorrow so that I can
deal with any buildfarm indigestion before committing swap mode.  I did run
the test locally for upgrades from v9.6, v13, and v17, but who knows what
unique configurations I've failed to anticipate...
