Hi,
Are there highly efficient C extensions out there for math operations on arrays? Dot product and whatnot.
what you mean "highly efficient" ?
PostgreSQL executor is interpret - so in almost all cases the special optimizations has not big sense. If you take few us, you will lost in executor.
Example usecase: sort an item by euclid distance.

Kind regards,
Marcus
