snuyanzin opened a new pull request, #27460:
URL: https://github.com/apache/flink/pull/27460
## What is the purpose of the change
Right now if there is `MATERIALIZED TABLE` with non persisted columns an
attempt to alter query will fail since there is an old validation. This
validation makes sense (at least in order to keep former functionality) for
persisted columns. In case of non persisted these columns should be excluded.
## Brief change log
MaterializedTableUtils and tests
## Verifying this change
extra tests added + existing tests for the same validation which cover lots
of persisted columns cases
