I am new to PostgreSQL and I have the following table: Name, City "Alex", "Washington" "Aleex1", "Washington" "Bob", "NYC" "Booob", "NYC" I want to "merge" similar rows based on levenshtein distance between names so that I have the following table: id, Name, City 1,"Alex", "Washington" 1,"Aleex1", "Washington" 2,"Bob", "NYC" 2,"Booob", "NYC" How could I do that on PostgreSQL? Is there an SQL command for this?
