Hi,
I wonder if it is possible to somehow benchmark your clustered index
implementation.
I tried to create VCI index for lineitem table from TPC and run Q6 query.
After index creation Postgres is not using parallel execution plan any

Yes, that' correct. Currently with this approach, it is not possible to
ditch the
heap completely. This approach is useful for the cases, where the user wants
to store only some columns as part of clustered index.
Ahh, that's unfortunate. Billion row+
