+1 on the general change of xlog -> wal.
That said, I'd also like to see a --force or similar option or mechanism
put in place to reduce the risk of users trashing their system because
they think pg_resetwal is "safe." ("It's just gonna reset things to make
the database start again, should be fine.").
pg_destroydb almost seems like a better choice, though I suppose
'pg_clearwal' would be more acceptable. Doesn't have quite the same
impact though.
Not sure on the best answer here, but it's definitely foot-gun that some
users have ended up using on themselves with depressing regularity.
Thanks!
Stephen
