Thanks, @AndrewCLion .

@VitalyBruk this is your script, please fix it as per Andrew's suggestion: https://github.com/MadeiraData/MadeiraToolbox/blob/master/Health%20Check%20Scripts/Find%20overlapped%20statistics%20%2B%20DROP%20statement.sql

You can use this script for Redundant Indexes as reference as it is a similar use case: https://github.com/MadeiraData/MadeiraToolbox/blob/master/Best%20Practices%20Checklists/Redundant%20Indexes%20Detailed.sql#L89
