Well, I do use select() before calling PQconsumeInput, but I'm not sure what
an event loop would be like.I have more than one (remotly executed) queries
and I want to pick whatever results are available without being blocked (and
even abord a delaying query), i.e. I do have other work to do. Having said
that, I think that an event loop would be appropriate but I'm a little
confused on its structure. Any pointers?
