 Unfortunately, primary keys, unique constraints and foreign keys do not
inherit to children in a meaningful fashion. It's one of the big
deficiencies right now.




Too bad. Table inheritance is pretty meaningless without these
abilities. Anyone working on them? In the meantime, I will go back to
views and updating the underlying tables.



There's noone actively working on it at the moment that I know of (and if
there is, hopefully they'll see this and correct me) although I believe
there was some noise in the last dev cycle of people thinking about the
unique (and pkey) side of it.


Thanks. I would think that if the primary and unique keys worked
properly the foreign key problem would just fall out naturally. I would
volunteer for this except I do all my programing in JAVA these days and
my C and C++ are too rusty to be useful.

I hope someone picks this up. It would go a long way in doing away with
the problems of views and inserts and updates.
