Correct. For that matter, Oracle table partitioning introduces significant
overhead, from what I've seen. I don't think there's a way not to.
Generally, I counsel people that they only want to consider
pseudo-partitioning if they have one axis on the table which is used in 90%
or more of the queries against that table.
What would improve the situation significantly, and the utility of
pseudo-partitioning, is the ability to have a single index span multiple
partitions. This would allow you to have a segmented index for the
partitioned axis, yet still use an unsegmented index for the other columns.
However, there's a *lot* of work to do to make that happen.
