... but execution times did not change at all compared to 100%
fillfactor, why is this ? Does the HOT feature only work if a different
backend accesses the table concurrently ?
Thanks,

Hi,
I was playing around with PG11.2 (i6700k with 16GB RAM, on Ubuntu 18.04,
compiled from sources) and LLVM, trying a CPU-bound query that in my
simple mind should benefit from JIT'ting but (almost) doesn't.
