We could easily get rid of mdblindwrt --- there is no very good reason
that we use the relcache for I/O.  There could and should be a
lower-level notion of "open relation" that bgwriter and checkpoint
could use.  See recent discussion with Neil, for example.  Vadim had
always wanted to do that, IIRC.
