Problems caused by uppercase table names

**Describe the bug**
I just found out about this project and was about to give it a go, but it was failing me at first.

I'm using Postgres and I have a table named `MOCK_DATA`, but I get the error `relation "public.mock_data" does not exist`.

Obviously the capitalization is wrong, then I changed the table name to lowercase and I can run , but the options in the drop-down box are not updated, they are still uppercase

**Version:**
[0.33.47]
