That's pretty interesting; it suggests an actual PG bug.
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?
