More the other way around: pg_type_d.h is built from the authoritative
source files pg_type.h and pg_type.dat, according to the process

Why not? If it's the "Backwards compatibility" comment that's

only intended to apply to the CASHOID and LSNOID symbols.
Everything below that in pg_type_d.h is machine-generated.
