Oracle SQL Developer and PostgreSQL

Question

I'm trying to connect to a PostgreSQL 9.1 database using Oracle SQL Developer 3.0.04, but I'm not having any success so far.

First, if I add a third party driver on preferences, when adding a new connection there's no tab for PostgreSQL (it works fine for MySQL though). I'm using a JDBC4 version 9.1 driver, but I tried a JDBC3 of the same version and still get the same thing.

Second, there's nothing like manual configuration tab when adding a new connection. The closest is the Advanced option on Oracle tab, where I can provide a custom URL, but it fails because complains about the selected Driver (of course).

Finally, I got connected importing a connection from an XML file (contents below), but it displays only my schemas and doesn't show my tables inside them.

So, my question is: does Orable SQL Developer support PostgreSQL connections? Is there any other way to have my tables being displayed in the ObjectViewer?

Oracle SQL Developer 4.0.1.14 surely does support connections to PostgreSQL.

• download JDBC driver for Postgres (http://jdbc.postgresql.org/download.html)
• in SQL Developer go to Tools → Preferences, Database → Third Party JDBC Drivers and add the jar file (see http://www.oracle.com/technetwork/products/migration/jdbc-migration-1923524.html for step by step example)
• now just make a new Database Connection and instead of Oracle, select PostgreSQL tab

Edit:

If you have different user name and database name, one should specify in hostname: hostname/database? (do not forget ?) or hostname:port/database?.
