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 :)
Regards,
Joe.
