Does anyone know of some sort method, third party program, etc, that can accept data from a number of different sources, and push it into Postgres as fast as possible?
Depending on what you're doing using custom code to parse your data and then do multiple binary COPYs in parallel may be better.

Thanks!
How long can you run COPY? I have been looking at it more closely. In some ways, it would be simple just to take data from stdin and send it to postgres but can I do that literally 24/7? I am monitoring data feeds that will never stop and I don't know if that is how Copy is meant to be used or if I have to let it finish and start another one at some point?
