Right. At the moment, *all* the type names that support parenthesized
options are hard-wired into the grammar. I think this is probably
unavoidable because otherwise there is a conflict between interpreting
"foo(3)" as a type name and interpreting it as a function call. (But
if anyone can think of a way around that, I'm all ears.)
Since varchar(n) is SQL-standard syntax, can't you simply adopt the more
standard name for both databases?
