ActiveRecord::ConnectionAdapters::OracleEnhanced::Connection::describe can fail for long table/view names

[jmmorganMSTS]

Steps to reproduce

create table a_table_or_view_name_longer_than_thirty_characters ( id number );
create table a_short_table_or_view_name ( id number );

Run in rails console:

ApplicationRecord.connection; nil # pre-connect

class TestModel < ApplicationRecord
  self.table_name = 'a_table_or_view_name_longer_than_thirty_characters'
end

TestModel # failes

class TestModel2 < ApplicationRecord
  self.table_name = 'a_table_or_view_name_longer_than_thirty_characters'.upcase
end

TestModel2 # works with .upcase

class TestModel3 < ApplicationRecord
  self.table_name = 'a_short_table_or_view_name'
end

TestModel3 # works without .upcase

Expected behavior

ActiveRecord models with table_name larger than 30 characters should return results when the name is all lowercase.

Actual behavior

Accessing the model results in the error:

ActiveRecord::ConnectionAdapters::OracleEnhanced::ConnectionException ("DESC a_table_or_view_name_longer_than_thirty_characters" failed; does it exist?)

I believe this is being caused by a 29 + 1 character limit in the regexp used by ActiveRecord::ConnectionAdapters::OracleEnhanced::Quoting::valid_table_name?
