Description

Enhancement

Some explain-test cases will record the plan ID in the result file, which will be a burden when some optimization flow is changed, since plan ID allocation is sequential according to the allocation order or space.

Contributor guide

Research direction
Modify the explain test cases to ignore the plan id field in the result file to avoid sequential allocation dependencies.
