Best way to handle "read only" paritions

[Dave Johansen <davejohansen@xxxxxxxxx>]

We're using a time-based partitioning scheme for our data and so partitions become "read only" once the time covered by it has passed. We've been CLUSTERing those partitions but here's some questions I have:
Should we set the fill factor of the indexes from the default of 90 to 100?

Should we do anything with xids and freeze age?

Anything else?

Thanks,

Dave
