Re: fun fact about temp tables

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?

I`ve noticed interesting aspect in temp tables working. It appears

temp_buffers overflow.

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.
