METHOD:

1. Data element is a structured type that's conducive to loop (comma-delim string, ARRAY[], JSON ARRAY{}, etc. )

2. Use correlated in-line subquery (in the SELECT clause)

   1. Nest inner query: WITH RECURSIVE ... () CTE inside that sub-select

      1. Use correlated/lateral JOIN to main query to fetch current row

      2. Loop thru the recursive CTE positions in the array

   2. Return result to outer subquery

3. Return result to main query
