I can get error anyway on first select because of hint bit write.

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.How about out of space when we filling WAL files?What about it? That will be reported before committing, too. What Grigory wants would imply committing and then sometime later saying "oh, wait ... remember that data we told you we'd committed? We lied." Temp tables do indeed disappear at session end (and a fortiori after a crash), but that doesn't create an excuse for them not to have normal transactional behavior within the session. regards, tom lane -- Grigory Smolkin Postgres Professional: http://www.postgrespro.com The Russian Postgres Company |
