I think more attention should be given to the libpq side of this patch;
maybe have a 0001 with only the new libpq function, to easily verify
that it does all it needs to do.  It needs docs for the new function in
libpq.sgml; also I wonder if checking conn->status before reporting
values is necessary; finally, has the application any good way to check
that the values can be safely read after calling the new function?

Nit: the new libpq function name is not great with all those lowercase
letters.  Better to make it camelCase like the rest of the libpq API?

Thanks for the patch,
