Changelog entry (a user-readable short description of the changes that goes to CHANGELOG.md):

Fixed Unknown identifier (aggregate-function) exception which appears when a user tries to calculate WINDOW ORDER BY/PARTITION BY expressions over aggregate functions:

CREATE TABLE default.tenk1
(
    `unique1` Int32,
    `unique2` Int32,
    `ten` Int32
)
ENGINE = MergeTree
ORDER BY tuple()
SETTINGS index_granularity = 8192;
SELECT
    ten,
    sum(unique1) + sum(unique2) AS res,
    rank() OVER (ORDER BY sum(unique1) + sum(unique2) ASC) AS rank
FROM _complex
GROUP BY ten
ORDER BY ten ASC;

which gives:

Code: 47. DB::Exception: Received from localhost:9000. DB::Exception: Unknown identifier: sum(unique1); there are columns: unique1, unique2, ten: While processing sum(unique1) + sum(unique2) ASC. (UNKNOWN_IDENTIFIER)

The bug was introduced in #34632 .
