Hi Karl,

Yep.

> Do you need the table key to be btree?  Can it be hash? Hash partitioning doesn't necessarily play well with a btree index.
We are doing lots of inserts into it and it's a big table so I suspect a hash structure would be nasty.

We shied away from range partitioning as the key fields are increasing and we thought any range condition would quickly become poor.

Yes and No respectively.
