Thread: pgsql: Refactor confusing code in _mdfd_openseg().
Refactor confusing code in _mdfd_openseg(). As reported independently by a couple of people, _mdfd_openseg() is coded in a way that seems to imply that the segments could be opened in an order that isn't strictly sequential. Even if that were true, it's also using the wrong comparison. It's not an active bug, since the condition is always true anyway, but it's confusing, so replace it with an assertion.
