High Availability - Performace Scalability - Dyanamic Load Balancing

Hi All,

    I just came off an exibit and I was wondering if there ways to do clustering
in postgres.
    I envy mySQL because there's a application for clustering it...

    EMIC networks has this marketing tagline:
        High Availability - Performace Scalability - Dyanamic Load Balancing
    they are the one who provide this app... ( but its not open source )


Thanks,
