I have a website that runs reports on data from a postgres database. An average report takes about 10 minutes. I'd like to load balance it so I can have multiple people run reports without causing the login request to take forever. Also, it is rather important that data updated in the database be updated on all mirrors of it immediately - not with an hourly or daily update.
What I would most desire is a program that pretends to be a postgres server. I can log into it with psql, a jdbc driver, or php's pg_connect. When I do a select (no update) command, it will send that off to the least loaded mirror. When I do an update/insert/delete, it hits all the mirrors. Also, it can designate one database (most likely local to this pretend server) as the master so I can easily clone it to make more mirrors.
Does anything remotely similar to that exist?
