Interesting.

What that Close message is doing is closing the unnamed portal, which
is otherwise closed implicitly when the next one is opened.  That's how
single-query mode works: if you run a single portal, it'll be kept open.

I believe that the right fix is to not send that Close message in
PQsendQuery.
