Is there a plan for fixing this particular limitation? It's a pretty
serious problem for users,
and the suggested workaround (to create a separate non-partitioned table
which carries only the PK
columns which is updated by triggers, and direct the FKs to it instead
of to the partitioned table)
is not only a very ugly one, but also very slow.
