indexer panic with partitioned indexes

In RQG there are the following two tests: aggregate pushdown with partial indexes and aggregate pushdown with partial partitioned indexes. The former passes fine. The latter shows queries that are failing due to indexer crashing and still in warmup state after it recovers. I have uploaded the logs and the following is the rqg test command:
