You will have to use the current 2.0.0-alpha/beta release, I found that the 1.0.8 version didn't yet have the support.

Had the same issue on Postgresql 9.6. The 1.0.8 version compiled successfully on my Debian 9.4 and seemed to do the trick.

Just tried here on Safari 12.1.1 (OSX), getting some unusual behaviour with the box appearing small and almost off screen (right).
