That's a development activity. Enabling the WAL_DEBUG #ifdef by
default during the 7.5 development cycle would be uncontroversial, I
think.

It is? Why would this be useful for non-development activities?

(It may well be the case that we ought to report more or better
information about the status of the WAL subsystem; but WAL_DEBUG is
surely not the right mechanism for emitting information intended for
an administrator.)
