Add ANALYZE. To keep the desired MergeAppend plans, we also have to add a LIMIT everywhere so that the MergeAppend is chosen based on its lower startup cost. Otherwise the plain Sort over Append will be chosen because for small tables its cost is less.
Add ANALYZE after compression. The plan changes are expected, SeqScans are preferred over IndexScans and Sort over MergeAppend for small tables.
We would add extra Sort nodes when adjusting the children of space partitioning MergeAppend under ChunkAppend. This is not needed because MergeAppend plans add the required Sort themselves, and in general no adjustment seems to be required for the MergeAppend children specifically there.
