Postgresql can handle 200 connections (two tier) ?

Hi,

I want to know if are there real world cases of postgresql supporting 200
simultaneous connections in two tier application.

I'm asking because I'm considering postgresql for the next application I
need to write.

A bit off-topic but I want to hear opinion of developers about two-tier
versus tree-tier applications with this number of connections to a
postgresql database.

Thanks in advance
