We don't have anything that currently tests the Custom Scan interface
in the tree.  The question is how important that is, and whether it's
worth having what's basically a toy implementation just to demonstrate
that the feature can work.  If so, I think ctidscan is as good a toy
example as any; in the interest of full disclosure, I was the one who
suggested it in the first place.  But I am not entirely sure it's a
good idea to saddle ourselves with that maintenance effort.  It would
be a lot more interesting if we had an example that figured to be
generally useful.
