There are two implementations because REPLACE comes in two forms:
REPLACE(char, search_string , replacement_string)
REPLACE(char, search_string )
/* equivalent to specifying an empty string as replacement */
Using "overloading", both modules are declared to be specific implementations of the same logical function; based on the number and
types of arguments supplied, the database will decide which to invoke.
