Can you get a stack trace from that? See https://wiki.postgresql.org/wiki/Generating_a_stack_trace_of_a_PostgreSQL_backend Also, it's probably time you showed us the complete DDL definition for the tables you're working with. It's fairly hard to believe this would happen without something rather out-of-the-ordinary in the definitions. Or ... do you have any PG extensions installed? regards, tom lane
