Uh, did you have the postmaster shut down while you did that?

This looks like a collision between two processes both trying to create
the next segment of the xlog at about the same time.  But there are
interlocks that are supposed to prevent that.

I don't think you need to worry about the integrity of your data; the
panic reset should put everything right.  But I'd sure be interested
if you can reproduce this problem.
