I wonder if this requires what the standard refers to as a global
temporary table. As I read it (which may be wrong, I find the language
obtuse), a global temporary table is a temporary table whose structure
is predefined. So, you'd define it once, updating the catalog only once
but still get a table that is emptied each startup.
Ofcourse, it may not be what the standard means, but it still seems
like a useful idea, to cut down on schema bloat.
Have a nice day,
