No ... temp_tablespaces says it's okay to use any of the listed
tablespaces to keep temporary working files in, but it doesn't
say that those tablespaces can *only* be used for that.

The whole business of temp tables (as opposed to those invisible-to-SQL
working files) in such a tablespace is a separate issue, too.  I think
that the server would mostly survive having temp-table files disappear
during reboot, but it's not an officially supported or tested scenario.
