Re: What is the tuplestore?

Yes, pgsql_tmp, you ought to be looking for a sudden and drastic jump in
space utilization around the time of the error message. You're not
concerned with the current space utilization, but with the one around that
time, because, it probably got freed right after the error was raised.
How many times has this happened ? what kind of queries were running at
that time? can you identify something that could have required lots of
temporary space?
