Committed with that name.
In your original patch, this hunk in pg_config_manual.h:
+ * You can define these by editing pg_config_manual.h but it's usually

+ *
+ * ./configure --enable-debug --enable-cassert CFLAGS="-DUSE_VALGRIND"
+ *
+ * The flags are persisted in Makefile.global so they will be correctly

I don't think that necessarily works for all settings. Maybe we should
make a pass through it and ensure it all works sensibly, but that seems
like a separate project.
