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.
