The result we get out of the recursive CTE is the UNION ALL (or UNION, if we want to remove duplicates) of all the iterations of the working table - i.e. all their rows appended together to form a single results table. If that sounded a little confusing, then the best way...
The use of uniq ensures efficient version handling without duplicates. However, there are some potential improvements for robustness. Let's verify the maximum allowed length for the versions array in the database schema: Consider adding input validation: if (specificVersions) { // Validate input ar...
