issue #495 not fixed in 0.12.0, with postgres 9.6

please check the lastest comment at #495 (comment)

Essentially the problem is fixed in 0.10.0 but not in 0.12.0, possibly due to #747 ?

If it can be confirmed, please reopen the issue. Thank you so much.

My comment on the other thread below. I'm not opposed to adding the support, but it needs some thought on how we architect it so that we can maintain this project long term.

It would appear that support for postgres < 10 was missed in that PR. Postgres 9 is not a version that we test against in our CI system. It's end of support so we don't go out of our way to test on it, but we don't intentionally break compatibility when we can avoid it. I think we could add that second query back to support < 10, but it would require some work to architect a maintainable system to handle different queries for different server versions.
