Re: Difference in execution plans pg12 vs pg14

Hi Dmitry,

pg12:
> Execution Time: 44.123 ms

pg14:
> JIT:
> Functions: 167
> Options: Inlining true, Optimization true, Expressions true, Deforming
true
> Timing: Generation 9.468 ms, Inlining 55.237 ms, Optimization 507.548
ms, Emission 347.932 ms, Total 920.185 ms
> Execution Time: 963.258 ms

please check the JIT settings ;
and test with: jit = off;

regards,
Imre
