So PostgreSQL is supposed to be object-relational. What is that and how
should I design my applications with that in mind? There are plenty of
texts out there on plain'ol RDBMS, I haven't seen anything that takes a
ORDBMS spin on it.

I guess what I'm missing is where or what the objects are. I've already
got overloaded functions and I tried to work with inherited tables (but
they didn't work the way I expected them to). Is that all that ORDBMS is?

About the inherited tables, I had hoped to have a parent with children
where fkey constraints held against the parent and cascaded to the
children (say person id where child tables are different types of people).
