Line 296 was replaced by line 297
- ***** The “nested” transpose is basically a combination of various lower-level algebraic operators, such as (theoretical) group-by, matrix transpose, projection, etc. So, give q as such a plan of operators, can we reason over the operators (white box-actors) q to obtain S*’? Using symbolic manipulation? Using the chase, e.g., for similar problems in integrity constraints?
