Comment (by David Sanders):
Is there some context missing here? From the details you've given, it is
sorting by rank 🤔
{{{
sample=# table ticket_34860_window_order_by_a;
id | a
----+---
1 | a
2 | b
3 | c
4 | b
(4 rows)
sample=# SELECT "ticket_34860_window_order_by_a"."id",
"ticket_34860_window_order_by_a"."a",
count('id') OVER (PARTITION BY
"ticket_34860_window_order_by_a"."a") AS "rank"
FROM "ticket_34860_window_order_by_a"
ORDER BY 3 ASC ;
id | a | rank
----+---+------
1 | a | 1
3 | c | 1
2 | b | 2
4 | b | 2
(4 rows)
}}}
