Enforce __pg_log_level message filtering centrally in logging.c, instead of relying on the calling macros to do it. This is more reliable (e.g. it works correctly for direct calls to pg_log_generic) and it saves a percent or so of total code size because we get rid of so many duplicate checks of __pg_log_level. This does mean that argument expressions in a logging macro will be evaluated even if we end up not printing anything. That seems of little concern for INFO and higher levels as those messages are printed by default, and most of our frontend programs don't even offer a way to turn them off. I left the unlikely() checks in place for DEBUG messages, though. Discussion: https://postgr.es/m/3993549.1649449609@sss.pgh.pa.us
