Pushed, after rewording the commit message a little bit, and removing
the sentence in the docs saying

(before PostgreSQL 19 the default was on)

We've changed the defaults for a number of GUCs over the years (and some
of the GUCs were more critical than "jit"), and we have not added
similar comments to those. I haven't found a single GUC with such
comment, actually. So why have it for "jit"?

regards
