I am finding out for the first time that by having a database created
with the name: MyTest, I cannot do a simple query as follows:

ERROR: cross-database references are not implemented: mytest.public.cars
Notice, however since I created a cars table
This error probably does not have anything to do with the case of your
database name. Instead you probably logged into a database which is not
MyTest, because it is not possible to log into a database x and make a
query on database y.
