Hello All,
 
We have a pl/pgsql function functionName(date) .. here if it has been called using functionName('23456') it gives error .. we need to raise an exception(customized error message) if the passed value is not date.. how can we do that.
 
Thanks..

You can add a function with the same name that accepts a text
parameter instead of a date. Then check the date and call your
functionName(date) function or raise your custom exception if the
date is invalid.
