As far as I have been able to determine, outer joins are not
supported in PostgreSQL.

I didn't see a response for this, so here goes... I believe
you can implement joins using the followng syntax:
select t1.value from table_one t1, table_two t2 where t1.key
= t2.key;
So this would be a straight LEFT join in my understanding.
Now, I'm venturing beyond my experience with PostgreSQL here, but you
may be able to use the associated SQL syntaxes:
select ... where t1.key *= t2.key select ... where t1.key =* t2.key
etc...
I hope I'm right here :)
