Well, presumably the code you'd need to look at lives in
src/backend/access/heap somewhere, or even just changing
the HeapTupleSatisfiesVisibility() macro in src/include/utils/tqual.h always
to return true. If you were to write your own app, after doing the above you'd
need to strip the heap access stuff out of postgres and build your app around
it. I think.
