I don't know about user wishes directly, though I do suspect fixed partition
stride would cover more than 25% of uses cases.  I do know that SQL Server,
Oracle and MySQL have variable-stride range partitioning, and none of them
have fixed-stride range partitioning.  So, like Heikki and Robert, I would bet
on variable-stride range partitioning.
