thanks a lot all for comments. So in PostgreSQL each query is a
transaction ?
Well the point was not to have a comparation with Oracle but to try
understanding the model what PostgreSQL does. It is interesting.
If you are under Oracle and say:
INSERT ...
UPDATE ...
and that's all another user will not see those updates if you don't COMMIT
the changes. After COMMIT all other users can see the changes.
In PostgreSQL the changes are visible as long as you run the query.
