From fb958b5da86da69651f6fb9f540c2cfb1346cdc5 Mon Sep 17 00:00:00 2001 From: Alvaro Herrera Date: Fri, 2 Dec 2022 10:35:55 +0100 Subject: Generalize ri_RootToPartitionMap to use for non-partition children ri_RootToPartitionMap is currently only initialized for tuple routing target partitions, though a future commit will need the ability to use it even for the non-partition child tables, so make adjustments to the decouple it from the partitioning code. Also, make it lazily initialized via ExecGetRootToChildMap(), making that function its preferred access path. Existing third-party code accessing it directly should no longer do so; consequently, it's been renamed to ri_RootToChildMap, which also makes it consistent with ri_ChildToRootMap. ExecGetRootToChildMap() houses the logic of setting the map appropriately depending on whether a given child relation is partition or not. To support this, also add a separate entry point for TupleConversionMap creation that receives an AttrMap. No new code here, just split an existing function in two.
