Hi All,
I managed to start CSS archive.engine on a MySQL db, now I am trying to 
get it started on a Postgresql db.
I am on a PC running Ubuntu 1204 using:
Java: JDK SE Dev Kit 7.51
Eclipse fro RCP and RAP Developers ver 1.4.2
SNS Sources 3.2.14
I installed postgresql 9.1 and loaded the schema with:
   sudo -u postgres psql < 
~/css/sources/org.csstudio.archive.rdb/dbd/postgres_schema.txt
So smpl_eng has the Demo engine in it:
1, Demo, Demo Engine, http://localhost:4812
I edited postgresql's pg_hba.conf file
      host    all             all 127.0.0.1/32            md5
      host    all             all             10.0.0.1/24     md5  # 
Added this line

In Eclipse I edited:
org.csstudio.archive.engine
  plugin_customization.ini file
org.csstudio.archive.rdb/url=""
and
org.csstudio.archive.engine.rdb
  preferences.ini file
    # Postgresql example
url=""

Before Launching the ArchiveEngine.product I added
Program Arguments using the 'Launching' tab
        -engine Demo
        -port 4812

On Launching I got the following in the Eclipse Console:
2014-03-03 23:11:01.753 INFO [Thread 1]
