I've marked this commitfest item[1] as Returned with Feedback.  Please
feel free to reopen it once you have an updated patch to share.  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?
