DB Connection is not closed automatically and close function fails

[sar009]

Describe the bug
The established db connections are not closed automatically when the data diff is completed more over when calling for close() it throws an attribute error since super has no close function.

from data_diff import connect

uri = "redshift://user:[email protected]:5439/dev"
database = connect(url, 1)
database.close()

the code above throws the following error

AttributeError                            Traceback (most recent call last)
