So I am able to see effect of jit_tuple_deforming, and very well, but
only if optimization is active. When optimization is not active then
jit_tuple_deforming does slowdown.
So maybe a usage of jit_tuple_deforming can be conditioned by
Hi
I played with it and maybe I got interesting result.
When I played with really big table, then I got IO waits and effect of
jit_tuple_deforming is near to zero (as expected)
When I played with smaller table under RAM, then I can see positive effect
of JIT_TD, but only when optimization is

Unfortunately I got slowdown
Hi
I try to measure effect of JIT tuple deform and I don't see any possible
effect.
Is it this feature active in master branch?
Is possible to see this feature in EXPLAIN ANALYZE?
