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? On 08/05/2016 05:51 PM, Tom Lane wrote:

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. regards, tom lane -- Grigory Smolkin Postgres Professional: http://www.postgrespro.com The Russian Postgres Company |
