Thank you for your answer.
But it`s temporary table so it`s equal to saying 'I don`t care about
this data' and I can get 'out of disk space' regardless of using
temporary tables.
What are we winning here?

Sure. Just like it reserves space for ordinary tables right away,
long before there's any need to push the data out of shared_buffers.
Otherwise, you might find yourself having to throw an "out of disk
space" error after having already committed the relevant INSERTs.
