No.  Generally, table partitioning is not a good idea unless you are
dealing with really large tables, and nearly all of your queries apply
only to a single partition.  Most likely you are better off not using
table inheritance in the first place if you need this feature.

It would be nice if we had a way to do this for the rare cases where
it would be useful, but we don't.
