Probaly if you change your postgres query to this, it will give the same
answer as Oracle:
select yt1_name, yt1_descr, yt2_name,
yt2_descr from
yuva_test1 left outer join yuva_test2 on yt1_id=yt2_id where yt2_name =
'2-name2';

And maybe if you change the oracle query to this, it will give the same
answer as postgres:
select yt1_name,
yt1_descr, yt2_name, yt2_descr from yuva_test1, yuva_test2 where
yt1_id=yt2_id(+) and yt2_name = '2-name2'(+);
Just guessing tho.
