Hi,
Browsing the PostgreSQL 12 release notes I noticed that JIT is now
enabled by default. Having not followed PostgreSQL development
closely -
does this mean that compilation results are now getting cached and
compilation is no longer executed separately for each worker
thread in a
parallel query ?
I don't know, but just want to chime in with my experience with PG-12
and JIT: Execution-time is still way worse then JIT=off for your
queries so we'll turn JIT=off until we can mesure performance-gain.
Hm, that's a bummer. So I guess we'll also have to make sure JIT is
turned off when upgrading.
Thanks,
Tobias
