Ok. Are You want to say that the different behavior in sql engine and jdbc
code is normal?
why I can build sql statement like 'select from Base' and 'select from base'
while I have only one table 'base',
but  getTables(..., "Base", ...) and getTables(..., "base", ...) gives me a
diffenent result.
Where is the logic?
What about psql?
\d Base
\d base
gives me info about the table 'base'. but not jdbc getTables(). pretty nice.

I think the logic of things like getTables have to be the same as the sql
engine.
