All of primary key, unique and foreign key constraints don't currently
meaningfully inherit. For the foreign key case the reference goes only
to the directly named table so rows in the subtables are not considered
for purposes of validating the constraint. In addition, in a structure
where you have a primary key inherited, the child tables do not get the
constraint for uniqueness although that can be added by explicitly putting
the constraint on, however that won't prevent duplicates between the child
and parent nor between children. There are some marginally complicated
workarounds using a separate table that have been discussed on the lists
before and should be available in the archives.
I think I should build a macro for the above. ;)
