Well, our docs for temp_tablespaces says:
This variable specifies tablespaces in which to create temporary
objects (temp tables and indexes on temp tables) when a
<command>CREATE</> command does not explicitly specify a tablespace.
Temporary files for purposes such as sorting large data sets
are also created in these tablespaces.
Are you saying this is inaccorate?
