where does postgres keep the query result until it is returned?

Hi,

Where does postgres keep the query result until it is returned?
In the shared_buffers?
Or in extra memory that was not previously allocated, or something else?

What if the query result becomes very large, so that it won't fit into memory?

cheers,

WBL
