Attached a new version rebased over c8f78b616, with the grouping relation partitioning enhancements as a separate patch 0001. Sorry about the delay. I'd also like to change compute_append_parallel_workers(), as also mentioned upthread, such that disabling Parallel Append by setting parallel_workers=0 on a parent partitioned table does not also disable the partitions themselves being scanned in parallel even though under an Append. I didn't get time today to work on that though. -- Amit Langote EDB: http://www.enterprisedb.com
