locking only needed Partitions when inserting.

[Aner Mazursky]

In an highly write-intensive DB, we encounter many situations where one
We're going to great lengths to make sure we never read from a partition we write to, but it seems like insert (both insert select and insert values) lock the entire table, even though the could lock only the relevant partitions (the select have an explicit condition on the output, which can say what is the partition)...

Is there any easy way to avoid those locks?
