Sure: Marko's exec_query_single_row example looks like 100% reasonable
libpq code.  That said, I'd still spend a few cycles to think this
through and make sure we aren't walling ourselves off from 'copy free'
behavior, even if that's reserved for a future improvement.  In
particular, I'd like to explore if PQsetSingleRowMode() should be
returning a result.
