I'm afraid, I'm not used to SQL92 join syntax and almost all my experience
is in Oracle but how about:
SELECT t1.uid
, t1.xname
, t2.uid
, t3.uid
FROM table1 t1
INNER JOIN table2 t2 ON t1.uid = t2.uid

If someone knows this it would be great - because I'm still curious how to
solve it. However I just remodelled my db structure to eliminate the problem

Here's a question for the SQL guru's out there, which I've been trying to
solve for the last couple of hours. There's got to be a solution to this, but
somehow I can't find it.
Tables:

uid int PK,
uname varchar(64)
)

My mistake! When composing the email to state the problem, I accidentally
gave a wrong version of the join query.

the simplest way to do it seems to be adding a SERIAL column to your table, and then adding a primary key constraint:
1)insert data into table
2)ALTER TABLE ADD id SERIAL;
3)ALTER TABLE ADD CONSTRAINT _pk PRIMARY KEY (id);
you can check the docs for the SERIAL type: http://www.postgresql.or
explain select notificationID from NOTIFICATION n, ITEM i where
n.itemID = i.itemID;

Hash Join (cost=47162.85..76291.32 rows=223672 width=44)

That sounds nice and easy...
So, I would do something like 'ALTER TABLE' to generate the PK column? What
would be the best way to populate it? Is there an area of doco I should be
looking at?
Thanks,

Does it help if you decrease the value of random_page_cost? - That value
can be changed run-time, from within psql. If you find that a certain,
lower value helps, you

I'm using PostgreSQL 8.
I have two tables that I am doing a join on, and the join executes very
slowly.
The table called Notification has a text field called NotificationID,
which is its primary key. The Notification table also has an int4 field
called ItemID, and it has an index on the It
