I have created new database and new schema.

CREATE DATABASE banks_db;

CREATE SCHEMA Chains;

Database was created, but not schema, and when I try to create it one more time I get error:

SQL Error [2714] [S0001]: There is already an object named 'Chains' in the database.

And as you can see on screen (even after refresh), there is no my schema.

So, how can I create new schema?
