[GENERAL] how to port Oracle database to PostgreSQL?

[Vassilev, Lubomir G.]

ok, this is what's going on. i have this VB.NET application with Oracle 8.1.7 back end, but now i have to switch the whole thing to PostgreSQL. how do i do that? it's a big database, about 135 tables, a lot of views, triggers, a few stored procedures and functions. i understand there is some tool to do that.
