Converted back to draft. I had still a version locally where I use join instead of left join. |

Please check if this works as intended and supports all platforms (i.e. does the unsigned cast work on postgres as well?). We also optimized this exact query in #150, is it still slow? |

The Query is much faster (+15 minutes compared to under a second) with this cast and the cast to unsigned should always result in a biging.
