in ejabberd-2.0.2, pubsub_item is disk_only by default.
this table handles published items, and have nothing to do with  
offline messages.
default configuration comes with persistent items (stores 10 last  
published items on each node).
pubsub_item is also used to store PEP items.
do you mean you changed the default configuration ?

to lower size of that table you can disable PEP plugin and/or set  
pubsub#max_items to 1
in 2.0.x, due to item cache unavailability, disabling persistent-item  
is not supported.
