b38c920266
This patch does following: 1. Planner changes to create ChunkDispatch node when MERGE command has INSERT action. 2. Changes to map partition attributes from a tuple returned from child node of ChunkDispatch against physical targetlist, so that ChunkDispatch node can read the correct value from partition column. 3. Fixed issues with MERGE on compressed hypertable. 4. Added more testcases. 5. MERGE in distributed hypertables is not supported. 6. Since there is no Custom Scan (HypertableModify) node for MERGE with UPDATE/DELETE on compressed hypertables, we don't support this. Fixes #5139
