The customerIDs are GUIDs represented as 16-byte arrays. I can pass
them as encoded strings separated by commas or some such silliness. But
I don't see a nice clean split() function that returns me an array. :-(
Do you need one? Can't you just pass the array as one parameter?
The text form of an array is like
{value,value,value}
which shouldn't be that hard to deal with if you can generate the text
form of the individual bytea values.

That doesn't work. If I pass a string, then it is a string.
CREATE OR REPLACE FUNCTION CalculateTotals(
customerList character varying,
.
.
.
WHERE customerid = ANY($1);
Results in the error:
ERROR: op ANY/ALL (array) requires array on right side
I tried casting the character string to an array afterward:
WHERE customerid = ANY($1::bytea);
which results in:
ERROR: cannot cast type character varying to bytea
