The (+) method of performing outer joins is an Oracle proprietary
deviation from the SQL92 standard. No other database uses this.
The PostgreSQL, and SQL92 standard, method for performing outer joins is
to use and explicit join syntax:
SELECT *
FROM table_a LEFT OUTER JOIN table_b
ON table_a.1 = table_b.2
Please be careful using LEFT and RIGHT outer joins to get the joined
tables on the correct sides!
See:
http://www.postgresql.org/idocs/index.php?sql-select.html
for more information on JOIN syntax.

for articles on porting from Oracle to Postgres
