+       strings that need to be converted to use <literal>E''</>.  Also,
+       use two single-quotes ('') to embed a literal single-quote
+       in a string, rather than the PostgreSQL-supported syntax of
+       backslash single-quote (\').  The former is standards-conforming
+       and does not require the use of the E'' string syntax.  You can
+       also use the $$ string syntax, which does not treat backslashes
+       specially.
