While that theoretically will work, it leaves a bad taste in my mouth.
I have been thinking of proposing that we add a "pg_current_wal_file()"
function, or some such name, to return the name of the active WAL file.

I think you can reasonably assume that .history files won't show up
on-the-fly, since they are only created during a PITR recovery operation
on the master. It's not clear how this whole thing should track such an
operation on the master anyway :-(
