This test script works fine in HEAD: drop table if exists parttbl cascade; CREATE TABLE parttbl (a int, b int) PARTITION BY LIST (a); CREATE TABLE parttbl_1 PARTITION OF parttbl FOR VALUES IN (NULL,500,501,502); UPDATE parttbl SET a = NULL, b = NULL WHERE a = 1600 AND b = 999;
In v11, it suffers an assertion failure in ExecSetupPartitionTupleRouting. In v10, it doesn't crash, but we do get WARNING: relcache reference leak: relation "parttbl" not closed which is surely a bug as well. (This is a boiled-down version of the script I mentioned in https://www.postgresql.org/message-id/[email protected]) This seems to be related to what Amit Langote complained of in https://www.postgresql.org/message-id/[email protected] but since there's no foreign tables involved at all, either it's a different bug or he misdiagnosed what he was seeing. regards, tom lane
