So I tested both HEAD and v12 on current and current-5, both successful. 
That should cover current-1 and current-2, too. If you want me to test 
any other macOS versions inbetween, or any other PG versions, I can do that.

I would really like to upstream those kind of patches and see them 
backpatched - otherwise we need to carry around those patches for up to 
5 years in the distros. And in light of the discussion in [1] my goal is 
to reduce the number of patches carried to a minimum. Yes - those 
patches are simple enough - but the more patches you have, the less 
likely you are going to spot a malicious patch inbetween.

Best,

Wolfgang
