How to store and retrieve data with special characters (\n, \r, \f, \t) in the same format - Mailing list pgsql-sql

How to store and retrieve data with special characters (\n, \r, \f, \t) in the same format, because while storing \f treats data in strange way.

Example: ‘This is sample data \n \root\files.txt, \root\text.txt’

Sol: One way replaces \ with \\

Thanks
