Oid is unsigned, typmod is signed. We might be able to get away with it,
but -1 is treated specially in some places outside of the type-specific
functions, e.g. exprTypmod().

I haven't looked at all of these places yet, so maybe a few simple
changes would allow us to treat typmod as a full 32 bits. Or perhaps it
could just be expanded to a signed 64-bit int. What do you think?
