Re-sharing my thoughts as it looks like that my previous email did not reach the
mailing list (yet?): probably because the attachement mentioned below was too
large.

Thanks for the report!

Indeed, and that's what clang-tidy (misc-include-cleaner) also reports:

$ run-clang-tidy -checks="-*,misc-include-cleaner" | grep "is not used directly" | grep stat_utils.c
../src/backend/statistics/stat_utils.c:26:1: warning: included header lmgr.h is not used directly [misc-include-cleaner]

Actually it reports much more (see attached):

$ run-clang-tidy -checks="-*,misc-include-cleaner" | grep -c "is not used directly"
794

I did not look to check if all of them make sense (I'd guess probably not), but
I'm wondering if it would make sense to work an a "larger" cleanup instead?
(in the same vein as [1] did)
