There's a type called "char" (the double quotes are needed). It's used by
postgres system catalogues but it's available for users too. It's a little
quirky since it has operators that treat it as a 1 byte text data type and
other operators that treat it as an integer data type. But that doesn't
normally lead to any problems, just strange symptoms when your code has a bug.
Other than that there are things like bit(4) which has a cast to and from
integer. But they won't save you any storage space. If you have multiple
columns like this and want to define a new type that aggregates them all for
storage but lets you access them individually that could be useful.
