Description

The ALTER TABLE ALTER COLUMN operation has several limitations:

Cannot handle complex data type changes (e.g., from TEXT -> INT)
Cannot handle column index changes
Cannot handle renamed columns

Impact

These limitations affect schema evolution scenarios where columns need to be modified with complex changes.

Expected Behavior

Complex data type conversions should be handled automatically
Column index changes should be replicated correctly
Renamed columns should be properly tracked and updated

Current Behavior

Complex data type changes fail
Column index changes are not properly replicated
Renamed columns are not handled correctly
