Oh, good, that makes things much easier.

Hmm.  I guess it wouldn't be completely out of the question to expose
the contents of PGresult as part of libpq's API.  We haven't changed it
often, and it's hard to imagine a change that wouldn't be associated
with a major-version change anyhow.  We could do some things to make it
a bit more bulletproof too, like change cmdStatus from fixed-size array
to pointer to allocated space so that CMDSTATUS_LEN doesn't become
part of the API.

Alternatively, we could keep it opaque and expose a bunch of manipulator
routines, but that might be a lot more cumbersome than it's worth.
