And, is there anything like RAM-only tables? I really don't care whether the
staging data is lost on the rare event of a machine crash, or whether the
query crashes due to lack of memory (I make sure there's enough w/o paging)
- I only care about performance here.

I think can create a tablespace on a ram disk, and create a table there.

True, but I think this makes the database server configuration more complex (which is acceptable), and may add dependencies between the server configuration and the SQL statements for the selection of tablespace name (which would be a problem)?

But I am a tablespace-novice and will look into this "workaround".

 thanks, Joachim
