There are now 4 explain levels summarized as follows: - Level 0: MINIMAL Non-fragmented parallel plan only showing plan nodes with minimal attributes - Level 1: STANDARD Non-fragmented parallel plan with some details in plan nodes - Level 2: EXTENDED Non-fragmented parallel plan with full details in plan nodes including the table/column stats, row size, #hosts, cardinality, and estimated per-host memory requirement - Level 3: VERBOSE Fragmented parallel plan with full details (like level 2) This patch also includes several bugfixes related to plan costing and/or testing of explain plans.
