Hello,

I can't tell about JIT, it is too complicated for me ^^

Fwiw, Pierre Ducroquet wrote an article about another (faster)
implementation:

Xing Guo replied to his article by mentioning another two prototypes :

– https://github.com/higuoxing/pg_slowjit
– https://github.com/higuoxing/pg_asmjit

It is good to see interest in this area. Current implementation is quite
expensive and costing model risky. If often recommend disabling it and
enabling it when it is really needed. (It is disabled by default on AWS).
