OK for me.

Yes, thanks.

Thanks. You have more talent for naming than I do.

Just reading it again, I think that XLogFileNameById should use
MAXFNAMELEN, and that XLogFileName should call directly
XLogFileNameById as both are doing the same operation like in the
attached. It seems also safer to use MAXFNAMELEN instead of MAXPGPATH
for exclusiveCleanupFileName in pg_standby.c and pg_archivecleanup.c.
