How to configer the pg_hba record which the database name with "\n" ?

Hi all,

I've come across an issue within pg_hba configuration which it seems
cannot not set the record of a database name where there is a
newline(\n) in the name.

I created the database whihin psql like this:
create database "ab
cd";

I have tried all the following records, but seems not to work:
local "ab\ncd "user auth-method
local "ab\\\ncd "user auth-method
local "ab
cd "user auth-method

Does PostgreSQL 9.2's client authentication support to match the
database name with "\n" ?

Cheers
