Subject: pgsql: Injection points for hash aggregation.
Date: Tue, 11 Feb 2025 19:46:08 +0000
Message-ID: <E1thwCu-006baZ-2d@gemulon.postgresql.org> (raw)
Injection points for hash aggregation.
Requires adding a guard against shift-by-32. Previously, that was
impossible because the number of partitions was always greater than 1,
but a new injection point can force the number of partitions to 1.
