Right, it's harmless AFAICS. And it might actually be useful to be able
to prepare all queries right after connecting, even though the
connection is in not yet read-write.
It's the documentation (in source code or README) that's lacking, and
perhaps we should add more explicit checks for the "can't happen" cases,
just in case.
