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 canimplement 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'mventuring beyond my experience with PostgreSQL here,
butyou may be
ableto use the associated SQL syntaxes:
select ... where t1.key *= t2.keyselect ... where t1.key =* t2.key
etc...
I hope I'm right here :)
Regards,Joe.
