Here's a patch to add the sum of timings for JIT counters to
pg_stat_statements, as a way to follow-up on if JIT is doing a good or
a bad job in a configuration.
I decided to only store the total time for the timings, since there
are 4 different timings and storing max/min/etc for each one of them
would lead to a bit too much data. This can of course be reconsidered,
but I think that's a reasonable tradeoff.
Another option I guess could be to store the max/min/etc, but only
store for the total jit time instead of for each individual one. Maybe
that'd actually be more useful?
