It is possible to replace many occurrences of builtins.h with
fmgrprotos.h.  I just tried this  git grep -l 'include.*utils/builtins.h' -- *.c | xargs perl -pi -e
's{utils/builtins.h}{utils/fmgrprotos.h}'
There's a large number of changes that the oneliner produces that must
be reverted for the compile to be silent, but a large portion can
remain.  (I only tried src/backend/access).

Anyway I support the idea of creating other header files for specific
purposes, such as ruleutils.h, varlena.h, etc.  (I am against creating a
header file that contains commonly used macros such as
CStringGetTextDatum together with varstr_sortsupport.  I think the
latter should have its own place).
