I was and remain pretty dubious of this idea. In the backend in
particular, there is very little code that could usefully be tested
in a stand-alone fashion. For instance, almost everything assumes
the presence of palloc and elog and related facilities, and most
things depend at some level on having catalog data, and there are
lots of complicated, frequently-changed data structures involved in
the APIs. I think you'd spend vastly more time constructing and
maintaining unit-test cases than would ever be repaid :-(
