Обсуждение: 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.
