Unfortunatelly this is not very productive when sSrc or sDst has to be 
constants inside the function. There is another workaround for that, to 
specify '\' as chr(92). For instance:

CREATE OR REPLACE FUNCTION myformat(sText varchar)  RETURNS varchar AS 
$BODY$
BEGINRETURN replace( sText, chr(92), '\\' );
END;
$BODY$ LANGUAGE 'plpgsql' VOLATILE;

Consequently, the statement SELECT myformat('a\b' ) will get the desired 
result a\\b
