 From your description I don't see evidence that you should need to 
partition your table at all. A 1GB table is very common for pgsql. Spend 
some hard disks on your storage subsystem and you'll gain the 
performance you want, without trouble on the SQL side. For specific 
requirements, you might see improvements from partial indexes.
