Intelligent Database in postgreSQL

["Rodrigo Faccioli" <faccioli.postgresql@xxxxxxxxx>]

Hi,

I'm a new user's postgreSQL and I have a question: Is possible add function of intelligent System like Neural Networks or Fuzzy Logic within postgre SGDB?

For example: I have a database and I want to execute a select instruction. But, this select constains there is  column  that uses a Perceptron Neural Networks  for return a result, 
follow below:

        Select perceptron(vendas_cli)
        from client
        Where vendas_cli > 1000

Thanks,
