There is no "list" data structure in SQL. There are tables, and there
are arrays, but it's not especially easy to pass an arbitrary table
value to a function. So you almost certainly need to define your
problem as "create a function that accepts an array then ...".

I could always try converting the array_sort, array_uniq int[] C function to accept text[], but I decided to ask and see if there was a simplier/standard way first since I don't know C all that well.
