I am not saying that we should support two token types in general. Only
the SQL types. We already do that anyway, like (kind of)

Type: CHARACTER VARYING { $$ = "varchar"; }
| etc.

All I'm saying is that we add

| BIT VARYING { $$ = "bit varying"; }

No problem so far, right? Especially, if this is dumped out, then it
becomes bit varying without any extra effort.

The only problem is that with the current syntax the bootstrap scanner
cannot insert fields that contain spaces. Simple fix there, and we're
done.

To be clear again: I am not vaguely suggesting that we support any
multi-token types. I am just saying that we shouldn't introduce any new
and unnecessary external/internal type discrepancies just because the
bootstrap scanner is stupid.
