* However, there are several cases when this optimization is not safe. If
* the rel isn't partitioned, then none of the paths will be Append or
* MergeAppend paths, so we should definitely not do this. If it is
- * partititoned but is a joinrel, it may have Append and MergeAppend
- * paths, but it can also have join paths that we can't afford to discard.
