Interesting. Still, I think you'd be in better position than anyone
else to come up with reproduction steps for vanilla PostgreSQL by
analyzing the stack trace if and when the crash next occurs (or using
the existing core dump). It's hard to tell by only guessing what may
have gone wrong when there is external code involved, especially
something like Citus that hooks into many points within vanilla
PostgreSQL.
