Could it make sense to do this as a auto_explain feature?
It could be. But I was looking for something a lot more "light weight" than having to install an extension. But yes, if we wanted to, we could certainly change jit_warn_above_fraction to be auto_explain.log_min_jit_fraction or something like that, and do basically the same thing. But then, we could also have log_min_duration_statement be part of auto_explain instead, so it's all about where to draw the line :) -- Magnus Hagander Me: https://www.hagander.net/ Work: https://www.redpill-linpro.com/
