Do not shutdown on binding error

[fishcakez]

This is a bug fix for tag v0.10.0. The bug is fixed on master by coincidence. Could we have a branch for v0.10 so we can backport fixes without introducing prepare/execute into v0.10.*? This PR is not mergable.

This bug was reported in #129 but was hidden by an issue with Ecto (see elixir-ecto/ecto#1161).

Ah, 6210d10 fixes the issue so not by coincidence. I am unsure we need a v0.10 branch then but we should cherry pick the test in this branch.

I am unsure if we need to tag a patch release. I just would have preferred not to tag a release with prepare/execute because the API changes slightly in #128. I am happy with whatever @ericmj would like to do though.

If it's already fixed I don't see the need for a new release that just adds a test? If v0.11 takes time and other fixes are needed for v0.10 we can cherry-pick this. Sounds good?

[fishcakez]

Yeah sounds good. I am unsure how frequent a binding error is. https://gitub.com/ericmj/postgrex/commit/6210d103da812e2478785859ea241ed07faa1bec can be applied to v0.10.0 so anyone facing this issue can use that in the meantime. I have rebased on master so we can merge the test.
