Hi!

This topic has already been discussed in [0], I believe. I'm not sure how
it all ended and if there were any changes made in the end. But from the
user's perspective, temporary tables are expected to be isolated within
sessions, I think. This is an ideal solution, but does it feasible or not
is a question.

BTW, if we can "isolate" temp relations, we'll be one step close to get rid
of temp relations locking [1].
