Nope. What you described is a "not normalized" table. ;-)
One project contains a Notes table. However, I want it to be
configurable to what records notes apply ... that is, my application has
an admin option that allows you to configure the system so that there
are or aren't Notes for Client Addresses, for example.
TO do this, I created a sequence that is generally available
('universal_sq'), and set 7-9 tables to automatically increment a value
from the 'universal_sq' (column 'usq') for each record.
The Notes table, thus, effectively has the 'usq' as a foriegn key for 2
to 7 other tables, depending on user configuration. The wonderful
PostgreSQL sequence handler makes this possible. Thanks, Tom & team!
I've done this with a couple of other tables. Not relationally correct,
but I can't find anything wrong with the idea.

I believe that Christof posted the correct URL.
