Sure, there should be *a* way to do that. It does not have to be as
easy as "change an environment variable". And in fact the primary
objection to this patch is exactly that it is *not* as easy as "change
an environment variable" --- what you get if you just change your
environment variable is not a moved xlog, but a broken database.
Possibly an irredeemably broken database.
