If so, they are supposed to include it for themselves.
Note: you can't really include ALL sys headers first, since some of them
need to be included conditionally, and the condition symbols are coming
from config.h...

OK, so then no .c files should be including c.h directly anymore?
Everything should include either postgres.h, or config.h if it's
not tightly tied to the system?
