No.
I think Hiroshi or someone put in a function you can use to follow the
chain, but a simple "WHERE ctid = whatever" won't do it. In any case,
if you're not holding an open transaction then you have to be prepared
to have the dead tuple vacuumed out from under you, in which case you'd
not be able to follow the chain anyway.
