The code beginning at freelist.c line 645 is intended to deal with this.

I dislike exposing such low-level issues to AbortTransaction().
If an explicit reset is needed, there should be something like
an AtAbort_Buffers() call that does this as well as any other
low-level issues needed (eg AbortBufferIO()). Note that you
missed AbortSubTransaction() anyway.
