OK, turns out the failures were caused by the test creating a standby
from a backup, without a slot, so sometimes the primary removed the
necessary WAL. Fixed in the attached version.

There's still a failure on windows, though. I'd bet that's due to the
data_checksum/LocalDatachecksumVersion sync not working correctly on
builds with EXEC_BACKEND, or something like that, but it's too late so
I'll take a closer look tomorrow.
