Sv: JIT in PostgreSQL 12 ?

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.
