In the current version of postgres, it seems that Postgres aborts the query
and complains out of memery rather than creates temporary overflow files, when
postgres does join operation on two large files. In another words, postgres
does join operation only in memory rather than creating temporary files on
disk when overflow occurs. Am I right? What about in the next release?

Thanks in advance for any respones.
