Hi, In case of list partitioned table: 1. If there is a partition accepting only null values and nothing else, then currently the partition constraints for such a partition are constructed as "((a IS NULL) OR (a = ANY (ARRAY[]::integer[])))". I think there it is better to avoid constructing an empty array to avoid executing ANY expression.
2.Also, we are constructing an expression using index 0 of arrays in PartitionKey since currently we have only one column for list partition in key, added an assert for this. PFA. Regards, Jeevan Ladhe
