Hi Jochen,
I think you are correct. dependency=true is incorrect for postgresql.
I updated to a new postgres version at some point that contained the
DataSourceFactory. Before we had a postgres adapter that refered to a
postgres package.
So when it was still present this worked. Now quite possibly it does not.
I created the issue below and will commit a fix.
https://ops4j1.jira.com/browse/PAXJDBC-82
Btw. Ops4j is open for anyone willing to help. They do not have a voting
for committers. So if you are interested to help out I can explain you
how to get started.

Hi,
I just experienced the same behavior with Karaf 4.0.1 / pax-jdbc 0.7.0: the
PostgreSQL driver bundle is not installed, although there is no other DB
driver available. After manual installation, it works.
Would be nice if the pax-jdbc-postgresql feature would just work
"out-of-the-box". Is there already a Jira for this?
Is the dependendy=true correct at this place at all? What if I want to
connect to two different Databases from the same Karaf instance? If DB
driver 1 fulfills the depencencies needed by other bundles already, the
Postgres driver would never be installed. Or haven't I understood the
dependency mechanism correctly?
Best Regards,
Jochen

The adapter bundle is not necessary anymore for the newest postgresql
version as it already provides a DataSourceFactory.
I just tried to install pax-jdbc-postgresql 0.5.0 in karaf 4. The
problem seems to be that the postgres bundle is not being installed.
I only see the org.osgi.service.jdbc spec bundle.
The strange thing is that when I install the postgresql bundle by hand
it works fine.
install -s mvn:org.postgresql/postgresql/9.4-1200-jdbc41
When both are installed I see the DataSourceFactory.
service:list DataSourceFactory
[org.osgi.service.jdbc.DataSourceFactory]
-----------------------------------------
osgi.jdbc.driver.class = org.postgresql.Driver
osgi.jdbc.driver.name = PostgreSQL JDBC Driver
osgi.jdbc.driver.version = PostgreSQL 9.4 JDBC4.1 (build 1200)
service.bundleid = 54
service.id = 126
service.scope = singleton
Provided by :
PostgreSQL JDBC Driver JDBC41 (54)
No idea why it does not work with the feature. You can work around the
problem by defining a feature for your own application that load the
bundles using the mvn urls from the pax-jdbc feature file.

Compairing 4.0 and 5.0 feature files I found out that one bundle is
missed.
<feature name="pax-jdbc-postgresql" description="Provides JDBC PostgreSQL

There is no more adapter bundle in 5.0 for postgress. And karaf doesn't
create DataSource without an adapter.
Then I checked git repo: https://github.com/ops4j/org.ops4j.pax.jdbc.
There is no mention about postgress.
