    A sequence of characters bound by single quotes is contained by string constants. This feature is used when one needs to insert a character or to pass a character to database objects. PostgreSQL allows the usage of single quotes but embedded by a C style backslash. A string constant is a sequence of characters bound together by single quotes instead of double quotes, which is generally the case with string type variables. This feature is mostly used when a character is being inserted or when a character needs to be passed to database objects. This feature is exceptionally important while parsing data. PostgreSQL lets a user use single quotes only when it is embedded by the specific C-style backslash.
