I'm working on this. The summary at Phoronix isn't really accurate. The presentation linked is about a different effort to integrate JIT into postgres.

It's more for some queries (2.2X for Q01), less for others.
> Creating indexes was found to be even 5~19% faster with this JIT mode. Overall, quite promising improvements. "
There's no JITing done during CREATE INDEX atm. That'd be very worthwhile to do, but I just don't have the cycles to get it done for v11.
