Description

Migrated from [DBZ-4350](https://issues.redhat.com/browse/DBZ-4350)

This issue is a follow-up to DBZ-4272.

Further steps are necessary as the schema migration is more complicated - synchronization with change table switch.

Currently the code will end-up in an exception but the case could be identified via a log messages introduced in {{io.debezium.util.ColumnUtils.toArray(ResultSet, Table)}}.

Research direction

Read the DBZ-4272 follow-up and migrated DBZ-4350 context first, then inspect io.debezium.util.ColumnUtils.toArray(ResultSet, Table), where the current case is surfaced by a log message before the exception. Trace the schema migration and change-table switch interaction, and verify the behavior for an incremental snapshot launched immediately before or during migration.
