Hi Hackers, While reading contrib/pg_prewarm/autoprewarm.c, I noticed that it includes broader wait-event/statistics headers than it appears to need.
autoprewarm.c only uses PG_WAIT_EXTENSION for WaitLatch(). That macro is defined in utils/wait_classes.h, so the attached patch includes that header directly instead of pulling in pgstat.h and utils/wait_event.h. This is my first patch to PostgreSQL, so please let me know if I missed anything or if the patch should be handled differently. Tests: meson test -C build pg_prewarm/regress pg_prewarm/001_basic Regards, Dongpo Liu
