Thanks!  Did you look at the code?  The first patch is just some
cleanup, while the second could have adjustments?  For the second I went
with the minimal amount of work, and actually there is no need to make
ReadTransientFile() return a status per my study of ReadTwoPhaseFile()
in https://postgr.es/m/20180709050309.GM1467@paquier.xyz which must fail
when reading the file.  So patch 0002 depends on the other 2PC patch.
