Description
With the new Lateral and Unnest – if a Hash-Aggregate operator is present in the sub-query, then it needs to handle the EMIT outcome correctly. This means that when a EMIT is received then perform the aggregation operation on the records buffered so far and produce the output with it. After handling an EMIT the Hash-Aggr should refresh it's state and a continue to work on the next batches of incoming records unless an EMIT is seen again.
