I would've liked to give freezing a new opcode, but we've ran out of them (see htup.h).

Hardly ... we have plenty of unused rmgr id's still.

Good point.

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.

Not logging hint-bit updates seems safe to me. As long as we have the clog, the hint-bit is just a hint. The problem with freezing is that after freezing tuples, the corresponding clog page can go away.
