PostgreSQL armazena tabelas em lowercase, e o Oracle em uppercase. Por isso, para checar se a tabela existe, é necessária a checagem do banco de dados. Para o `SELECT` só é necessário transformar em uppercase para manter a compatibilidade com o Oracle, pois o PostgreSQL transforma em lowercase automaticamente, a não ser que cercado por aspas duplas.
