    People accidentally blowing away pg_clog or pg_xlog is a pretty
    common occurrence, and I don't think there's all that many tools
    that reference them. I think it's well worth renaming them.

Pretty sure every single backup tool or script out there is referencing
pg_xlog. If it's not, then it's broken...

No, not really. Consider a filesytem backup using archiving and base backups. It doesn't care one lick about pg_xlog. And I guarantee you that there are tons of people running a backup like that considering the same script would work all the way back to 8.2 (.1?).
