Method GeneratePvtCte(IReadOnlyList<FieldInfo>, string, string, string?)

Generates CTE-based PVT (NOT correlated - single pass!).
This is 47x faster than EXISTS-based approach on 15K objects.
Example output:
WITH pvt_cte AS (
SELECT * FROM (
SELECT v._id_object, MAX(v._Long) FILTER (...) AS "Age", ...
FROM _values v
WHERE v._id_structure = ANY($1)
AND v._id_object IN (SELECT _id FROM _objects WHERE _id_scheme = $2)
GROUP BY v._id_object
) pvt
WHERE pvt."Age" >= 30
)
