Support autocreate node entities on postgresl

Christian hi!

I see the changes in the patch are already committed but the original problem still actually persists. Is there any other work left for this other than tests?

Thanks,,

Run into the same issue. But in our case error happens in Select2::getValidSelectedOptions(). This patch solved the issue for us.

Works for me.

I fixed the CI pipeline and added postgres tests to it. The postgres tests are still failing
