This seems mostly sane, except I think you have not considered the
issue of when to clear the smgr_transient flag on an existing
SMgrRelation: if it starts getting used for "normal" accesses after
having by chance been used for a blind write, we don't want the
transient marking to persist. That's why I suggested having smgropen
always clear it.
Likewise, I think the FD_XACT_TRANSIENT flag on a VFD needs to go away
at some point, probably once it's actually been closed at EOXACT, though
there's doubtless more than one way to handle that.

I'm not excited about back-patching it...
