Thread: pgsql: Use appropriate tuple descriptor in FDW batching
Use appropriate tuple descriptor in FDW batching The FDW batching code was using the same tuple descriptor both for all slots (regular and plan slots), but that's incorrect - the subplan may use a different descriptor. Currently this is benign, because batching is used only for INSERTs, and in that case the descriptors always match. But that would change if we allow batching UPDATEs. Fix by copying the appropriate tuple descriptor. Backpatch to 14, where the FDW batching was implemented.
