The following bug has been logged on the website:

Bug reference:      13736

PostgreSQL version: 9.4.5
Operating system:   Linux
Description:

When dumping a DB whose name has a backslash in it, I get a warning like:

------
pg_dump: WARNING:  nonstandard use of \\ in a string literal
LINE 1: ...) AS description FROM pg_database WHERE datname = 'i have / ...
                                                             ^
HINT:  Use the escape string syntax for backslashes, e.g., E'\\'.
------

pg_dump should be using PostgreSQL’s own recommended syntax, should it not?
Is there anything that would break from making this change?
