### Describe the bug In datafusion/optimizer/src/optimizer.rs:271 when calling `assert_schema_is_the_same` prev_plan / new_plan are backwards. This causes an incorrect / confusing assert error, indicating the optimized plan is actually the original plan. ### To Reproduce Any optimization error that produces a schema change will reproduce this bug. In this particular case, the root cause of the schema change dropping timezone metadata for timestamps somewhere in the Optimizer rule `simplify_expressions`. Fixing this bug will help find the root cause. ### Expected behavior _No response_ ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
