Corrigindo o erro 'PLAN_TABLE' is old version

Quando é executado um explain e o mesmo utiliza uma PLAN_TABLE com uma versão inferior a versão do Oracle, é apresentada a mensagem 'PLAN_TABLE' is old version e o resultado do explain pode, em alguns casos não apresentar a informação do tempo de execução do comando .

O problema de 'PLAN_TABLE' is old version ocorre geralmente após o processo de upgrade da base onde o produto foi atualizado, porém o usuário ainda está usando uma versão antiga do PLAN_TABLE.

O primeiro passo que estarei realizando é a simulação do erro:
