Hi,
Compiling postgres with said option in CFLAGS really gives an astounding
number of warnings. Except some bison/flex generated ones, none of them
looks acceptable to me.
Most are just file local variables with a missing static and easy to
fix. Several other are actually shared variables, where people simply
haven't bothered to add the variable to a header. Some of them with
comments declaring that fact, others adding longer comments, even others
adding longer comments about that fact.
I've attached the output of such a compilation run for those without
clang.
Greetings,
Andres Freund
