Newbie-question

Are presently converting from mysql to postgresql, and my first 
newbiequestion is how to make all the rows in a result from a select 
just "swosh" by? That is, I dont want to see them page for page; just 
to scroll by so I can se the last line with the number of corresponding 
rows.

And is there a way to see how long time a query took to execute without 
running a EXPLAIN ANALYSE on the query?
