whats the persistence of these temporary tables? by design, they are
meant for relatively short lifespan uses, and as Tom said are only
accessible by the connection that created them, and when you're done
with them you should drop them.

now, if you mean 'temporary table' in another sense, like regular tables
you're using for storing temporary data, how are you cleaning this
'temporary data' out of them? truncate should free the disk space
they use where delete won't.
