"cannot modify commandid in active snapshot during a parallel operation"

Hi,

We are seeing an error while querying a columnar table on one of our clusters. This is Citus 12.1.2 on PostgreSQL 15.6, however same problem also appears in Citus 11 and PostgreSQL 14 per:

https://stackoverflow.com/questions/75753591/postgresql-citus-ctas-with-select-on-table-with-columnar-storage-runs-in-error

Is this unsupported, or a bug?

Thanks!

Hey Devrim,

Yes, unfortunately this is a bug that we couldn't allocate resources to fix yet.
