Are there any plans to support this kind of scenario?

Ciao,

Hello!

Is HOT in 8.3 used in the following scenario:
INSERT ...
DELETE ...
at the same ratio.

So for example current data is added every minute and all old data older
than 2 years are deleted.

Would the heap be bloated or is this avoided by the HOT feature of 8.3 and
nearly kept constant?

HOT doesn't help here...it only helps with updates and then only if
you are updating fields that are not indexed.  if your table has a
rolling set of data, for example a log file...you probably want to
look at table partitioning (either manual or built in).
