plpgsql-function returning a table?

Hi,

I have a query that is a little bit complicated and that should contain
one parameter. I need this stuff more often, so I thought to create a function
where I do something like select complexquery(2000); and as result I get the
table I want. Is this possible, or can I create parametrized views?
