PostgreSQL Adapter for NexJ - Create Test Environment

Setup the postgresql-connection

For testing the connection, the 'AllTests.java' is being used.

Installed the Installer version Version 9.0.1-1 from list of PostgreSQL downloads.
Installed the JDBC3 Postgresql Driver, Version 9.0-801 @ http://jdbc.postgresql.org/download.html and added it to the libraries in JDK
The driver class which is being used for NexJ Express Model is: org.postgresql.xa.PGXADataSource
The driver is loaded from RelationalDatabaseFragment.java and RelationalDatabase.java
Metadata is loaded from the particular driver
   /* MySQLAdapterTest.java */
      try
      {
         s_metadata = loadMetadata(ADAPTER_NAME);
      }

   /* SQLDataTest.java */
   protected static Metadata loadMetadata(String sAdapter)
   {
      Properties props = SysUtil.getConfigProperties();  // sets DEFAULT_CONFIG_URL = '/' + NAMESPACE + "/default.config"
      props = new Properties(props);
      props.setProperty(XMLMetadataLoader.CONNECTIONS_URL_PROPERTY, "/nexj/" + sAdapter.toLowerCase(Locale.ENGLISH) + ".connections");  // sets the properties to postgresql.connection
After all properties are loaded, it creates the connection through Connection Factory files.
