I just noticed this compiler warning in a CI run, [16:06:29.920] ../src/backend/executor/nodeWindowAgg.c:3820:16: warning: ‘datum’ may be used uninitialized [-Wmaybe-uninitialized] [16:06:29.920] 3820 | return datum; [16:06:29.920] | ^~~~~ [16:06:29.920] ../src/backend/executor/nodeWindowAgg.c:3719:25: note: ‘datum’ was declared here [16:06:29.920] 3719 | Datum datum; [16:06:29.920] | ^~~~~ The logic in this function looks somewhat wicked. -- Álvaro Herrera PostgreSQL Developer — https://www.EnterpriseDB.com/
