If you do
postgres=# create user "HU";
You will get the "HU" as you want. Usage of the quotation marks is in the
manual.

Just cite Tom's post:
The difference between what PG does and what the spec says can only be observed when you sometimes double-quote a
particularidentifier and sometimes don't. PG makes FOO, Foo, foo and "foo" the same, but different from "FOO" or
"Foo";while the spec would have FOO, Foo, foo and "FOO" the same but different from "foo" or "Foo".
PostgreSQL is almost there and most of the problem is on the client side.
