Excerpts from Robert Haas's message of mié mar 21 21:50:24 -0300 2012:
> heap_freeze_tuple() was apparently designed at one point to cope with
> being called with either a shared or exclusive buffer lock. But none
> of the current callers call it with a shared lock; they all call it
> with an exclusive lock, except for the heap-rewrite code which doesn't
> take (or need) a lock at all.
> Since this is just dead code removal, I propose to apply this to 9.2.
