Hey, folks:

I haven't configured a PostgreSQL server since version 11 (before that,
I did quite a few).

What's changed in terms of performance configuration since then? Have
the fundamentals of shared_buffers/work_mem/max_connections changed at
all? Which new settings are must-tunes?

I've heard about new parallel stuff an JIT, but neither is that
applicable to my use-case.
