> we have seen issue in mat view for 3.11.1 where mat view
> 1) we have inserted a row in test table and the same recored is in test_mat
> table, with Enabled = true,
> 2) when I update the same record with Enabled = False, a new row is created
> in test_mat table(one with true and one with false) but in test table
> original record got updated to FALSE.
> 3) when I delete the record using Feature UUID then only the record with
> Fales is getting deleted in both the tables. however I can see the TRUE
> record in test_mat table.
> Issue is not reproducible in 3.11.2
