Do you have any better proposal? BTW, I am still not sure whether it
is a good idea to expose a new API for this especially because we do
exactly the same thing in existing function smgrnblocks. Why not just
add a new bool *cached parameter in smgrnblocks which will be set if
we return cached value? I understand that we need to change the code
wherever we call smgrnblocks or maybe even extensions if they call
this function but it is not clear to me if that is a big deal. What do
you think? I am not opposed to introducing the new API but I feel that
adding a new parameter to the existing API to handle this case is a
better option.
