getting "shell command argument contains a newline or carriage return:" error with pg_dumpall when db name have new line in double quote

Hi,
While doing some testing with pg_dumpall, I noticed one weird behaviour.

While we create the database, we are allowing the database name with a new
line (if name is in double quote).
*For example*:

> postgres=# create database "dbstr1;
> dbstr 2";
> CREATE DATABASE
> postgres=#

Here, the database name is in 2 lines.

With the help of pg_dumpall, I tried to dump but I am getting an error for
the new line.

--
> -- Database "dbstr1;
> dbstr 2" dump
> --
>
> shell command argument contains a newline or carriage return: "
> dbname='dbstr1;
> dbstr 2'"
>

After this message, we are stopping the dump.

I think, if we are allowing new lines in the db name, then we should dump
it.

Please let me know your thoughts about this error.
