Hi Alvaro and John,
> I think John's reservations on whether to absorb another requisite shared library is something to strongly consider -- I notice that x86-simd-sort is not yet packaged by Debian, for instance.
> Maybe your needs *are* served better by introducing simd-sort in pgvector after all? Alternatively: would it be too bad to reimplement simdsort in C within Postgres rather than using a third party library?
Thanks for your feedback and discussions here.

At this time, I'd like to withdraw the commitfest item [1]. The original developer who proposed the patch is no longer at Intel, and the x86-simd-sort library's future is also uncertain. Due to ongoing changes on our end at this time, we won't be able to support this work going forward. :- (
