Partitioned Tables Foreign Key Constraints Problem

Hi all,

Have a problem related to partition tables.

We have the following schema's :

master -
id integer (PRIMARY KEY)
cid integer

child1, child2 are the child tables of master table. Here "cid" is the field
used for partitioning.

We have another table called
other_tbl -
id integer (PRIMARY KEY)
m_id integer (FOREIGN KEY FROM master(id))

Now the problem is, since other_tbl->m_id referenced from master->id, if we
try to insert any vales in "other_tbl" for m_id its checks it presence in
only master table and not in its child table. As the master table is always
empty in partitions tables a foreign key violation ERROR is being given.

How can we define the Foreign_key constraint on "other_tbl" based upon any
partitioned table field.

Currently PostgreSQL doesn't have any simple way to support this. There
are a few workarounds, but they're fairly awkward, such as a trigger to
check if the ID is correct.
