Yes, these are new with gcc 4.6. I have filed a bug about them:
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48778
All the other new warnings introduced by gcc 4.6 should be cleaned up by
now in the 9.2 branch. (There are more warnings in 9.1 whose fixes I
did not backpatch.) I am personally using
make COPT="-Werror -Wno-error=address"
to build PostgreSQL for the time being.
