Well, not sure about that - all of the three major hyperscalers disable JIT in their managed Postgres offerings (or at least used to when I last checked), and those are a major chunk of usage these days. Also, both the RPM and (since recently) the Debian/Ubuntu community packages have factored out the LLVM/jit part into their own packages and AFAIK they do not get installed by default. So while the GUC is on by default, a lot of users might not use JIT these days and not know either way. > What they don't do, is realize that things are slower > than they could be -- much less try to figure out why. Right. Michael
