Thank you both for diving into this, I really appreciate the clarity
this brings to the code.  I've applied both patches and compared the two
approaches.  I build and tested Peter's patches on macOS (15.5, M3 Pro)
using meson and found no issues.  It's clear you both had the same idea
in mind, but with slight differences in application.

I find VARDATA(DatumGetPointer(key_datums[I])) to be more clear
than VARDATA_D(key_datums[I]).  Yes, the line length suffers a bit but I
find it much more readable.

I'm +1 for changes like this, and this one in particular.


Just my $0.02, best.
