Okay. I can send the numbers to the function using this array
format: '{123,124,125,126}'
And the function receives those numbers in this format: CREATE OR REPLACE
FUNCTION public.PopContacts(varchar, int4[]).
But, I still can't use the $2 or the ListOfNumbers alias in the function
body. I get this error: "Unable to identify an operator '=' for
types 'integer' and 'integer[]' You will have to retype this query using an
explicit cast"
Any thoughts?
