> On Iceberg tables when "ALTER TABLE table DROP COLUMN x" fails if x is a 
> partition column, the error message is cryptic: Failed to ALTER table 
> 'table': Cannot find source column for partition field: 1001: x: identity(1).
> The error message should be improved to suggest that partition columns cannot 
> be dropped.
