Review of Pull Request #11437: Cluster table support alter

Summary:
This pull request aims to add support for altering cluster tables. It includes changes to the server_task.go, upgrader.go, and build_alter_table.go files. The changes involve adding a logger to the Upgrader struct in upgrader.go and removing the check for cluster tables in build_alter_table.go.

Review:

1. In server_task.go, the change to add the logger to the Upgrader struct seems appropriate. However, it would be helpful to include a comment explaining the purpose of the logger and how it will be used.

Suggestion: Add a comment explaining the purpose of the logger and how it will be used.

2. In upgrader.go, the addition of the logger to the Upgrader struct seems appropriate. However, it would be helpful to include a comment explaining the purpose of the logger and how it will be used.

Suggestion: Add a comment explaining the purpose of the logger and how it will be used.

3. In upgrader.go, the addition of error logging when upgrading new table columns, new tables, and new system views is a good addition. However, the error messages could be more descriptive and provide more context about the specific error that occurred.

Suggestion: Improve the error messages to provide more context about the specific error that occurred.

4. In build_alter_table.go, the removal of the check for cluster tables seems inappropriate. It is important to ensure that cluster tables are not altered, so this check should not be removed.

Suggestion: Revert the removal of the check for cluster tables and add a comment explaining why cluster tables cannot be altered.

Optimization:

1. The changes made in this pull request seem to be focused on adding support for altering cluster tables. However, it would be beneficial to include some tests to ensure that the changes work as expected and do not introduce any regressions.

Suggestion: Add tests to ensure the changes work as expected and do not introduce any regressions.

Overall, this pull request makes some appropriate changes to add support for altering cluster tables. However, there are some areas that need improvement, such as adding comments and improving error messages. Additionally, the removal of the check for cluster tables should be reverted. Adding tests would also help ensure the changes work as expected.
