The following bug has been logged on the website: Bug reference: 17727 Logged by: Oleg S Email address: oserov@clickup.com PostgreSQL version: 14.5 Operating system: Ubuntu 22.04 LTS Description: I have a query that consistently results in server crash and "server process ... was terminated by signal 7: Bus error" running on any replica or master of the DB. I also have a more generic query that also crashes other masters/replicas in prod environment but with 'Segmentation Fault'. I can't reproduce the same crash in other non-prod environments. I am unable to provide repro steps that could reproduce this error on a local machine and looking for more guidance how to debug/mitigate this error. The query below is a minimal query that reproduces this error. Removing more columns, clauses, changing conditions makes the error go away. Query: WITH union_table AS ( SELECT id, 'dummy', NOW(), 'dummy', NOW(), NOW(), NOW(), 'dummy', 'dummy', 'dummy', NOW(), NOW(), 'dummy', 'dummy', 'dummy', 'dummy', fingerprint, 'dummy', 'dummy', 'dummy', 'dummy', 'dummy', NOW(), 4000102944500000000 FROM sh0001.assets UNION ALL SELECT id, 'dummy', NOW(), 'dummy', NOW(), NOW(), NOW(), 'dummy', 'dummy', 'dummy', NOW(), NOW(), 'dummy', 'dummy', 'dummy', 'dummy', fingerprint, 'dummy', 'dummy', 'dummy', 'dummy', 'dummy', NOW(), 4000102944500000000 FROM sh0002.assets UNION ALL SELECT id, 'dummy', NOW(), 'dummy', NOW(), NOW(), NOW(), 'dummy', 'dummy', 'dummy', NOW(), NOW(), 'dummy', 'dummy', 'dummy', 'dummy', fingerprint, 'dummy', 'dummy', 'dummy', 'dummy', 'dummy', NOW(), 4000102944500000000 FROM sh0003.assets UNION ALL SELECT id, 'dummy', NOW(), 'dummy', NOW(), NOW(), NOW(), 'dummy', 'dummy', 'dummy', NOW(), NOW(), 'dummy', 'dummy', 'dummy', 'dummy', fingerprint, 'dummy', 'dummy', 'dummy', 'dummy', 'dummy', NOW(), 4000102944500000000 FROM sh0004.assets UNION ALL SELECT id, 'dummy', NOW(), 'dummy', NOW(), NOW(), NOW(), 'dummy', 'dummy', 'dummy', NOW(), NOW(), 'dummy', 'dummy', 'dummy', 'dummy', fingerprint, 'dummy', 'dummy', 'dummy', 'dummy', 'dummy', NOW(), 4000102944500000000 FROM sh0005.assets UNION ALL SELECT id, 'dummy', NOW(), 'dummy', NOW(), NOW(), NOW(), 'dummy', 'dummy', 'dummy', NOW(), NOW(), 'dummy', 'dummy', 'dummy', 'dummy', fingerprint, 'dummy', 'dummy', 'dummy', 'dummy', 'dummy', NOW(), 4000102944500000000 FROM sh0010.assets UNION ALL SELECT id, 'dummy', NOW(), 'dummy', NOW(), NOW(), NOW(), 'dummy', 'dummy', 'dummy', NOW(), NOW(), 'dummy', 'dummy', 'dummy', 'dummy', fingerprint, 'dummy', 'dummy', 'dummy', 'dummy', 'dummy', NOW(), 4000102944500000000 FROM sh0011.assets ) SELECT union_table::text FROM union_table WHERE id < 4000102944500000000 AND id > 0;
