PostgreSQL JDBC driver trouble for river plugin

I installed the elasticsearch-river-jdbc/1.3.2 by downloading the zip from https://github.com/jprante/elasticsearch-river-jdbc/downloads and installed by 'sudo ./bin/plugin -url file:///home/randel/elasticsearch-river-jdbc/elasticsearch-river-jdbc-1.3.2.zip -install river-jdbc'

Than I checked what JVM version is installed: 1.6 and downloaded the jdbc4-PostgreSQL driver from http://jdbc.postgresql.org/download.html. I copied it to /usr/share/elasticsearch/plugins/river-jdbc as well as /usr/share/elasticsearch/lib/.

Restarting shows:

but when I issue:
curl -XPUT 'localhost:9200/_river/my_jdbc_river/_meta' -d '{
"type" : "jdbc",
"jdbc" : {
"driver" : "org.postgresql.Driver",
"url" : "jdbc.postgresql://localhost:5432/testdb",
"user" : "",

"sql" : "select * from infolist"
}
}'

I get:
{"ok":true,"_index":"_river","_type":"my_jdbc_river","_id":"_meta","_version":1}

and in the log:

What is going wrong here? The driver is readable by everyone. Do I need to rename it or something?

Question answered, it is jdbc:postgresql not jdbc.postgresql
