Tom Lane be39d88934 Add regression test coverage for contrib/pg_buffercache.
We can't check the output of this view very closely without
creating portability headaches, but we can make sure that
the number of rows is as-expected.  In any case, this is
sufficient to exercise all the C code within, which is a
lot better than the 0% coverage we had before.
