 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.
