fix(postgres): support select with ordinality

[nguyenmp]

Postgres supports WITH ORDINALITY: https://www.postgresql.org/docs/18/sql-select.html

Example:

SELECT * FROM unnest(ARRAY['a','b','c','d','e','f']) WITH ORDINALITY;
 unnest | ordinality
--------+----------
 a      |        1
 b      |        2
 c      |        3
 d      |        4
 e      |        5
 f      |        6

This seems like a bug on master, master is out of date. Needs to regenerate this file.
