It is somewhat.  A workaround is to perform ALTER TABLE SET LOGGED
individually on each partition.  Specifying LOGGED / UNLOGGED for the
parent table is useless as things stand now.

Are you sure by the way that the individual partitions are themselves
UNLOGGED when you created them?  Partitions don't inherit the
logged-ness property from the parent table, so you must explicitly
create a partition using CREATE UNLOGGED TABLE ... PARTITION OF ... if
you want it to be unlogged.
