Just a bump to see if there is a time frame for a fix on this.

Google Cloud doesn't yet support setting the *enable_incremental_sort * flag
yet.
Was able to temporarily resolve by running the following though:

ALTER DATABASE corpdb SET enable_incremental_sort TO OFF;

Hope this helps others until the core issue has been resolved.
