Hardly ... we have plenty of unused rmgr id's still.
The real issue that still has to be resolved is the interaction of all
this stuff with PITR scenarios --- is it still safe to not log hint-bit
updates when PITR is on? I think it's premature to start writing
patches until we've decided how this really needs to work.
