How to configure WSO2 Carbon platform to work with PostgreSQL database?

Step 1: Database configuration for registry

   <dbConfig name="wso2registry">
        <url>jdbc:postgresql://localhost/[DATABASE-NAME]</url>
        <userName>[DATABASE_USERNAME]</userName>
        <password>[DATABASE_PASSWORD]</password>
        <driverName>org.postgresql.Driver</driverName>
        <maxActive>40</maxActive>
        <maxWait>60000</maxWait>
        <minIdle>5</minIdle>

    </dbConfig>

Step 2: Database configuration for user manager

 <Configuration>
    <AdminRole>admin</AdminRole>
    <AdminUser>
      <UserName>admin</UserName>
      <Password>admin</Password>
    </AdminUser>

    <EveryOneRoleName>everyone</EveryOneRoleName> <!-- By default users in thsi role sees the registry root -->
    <ReadOnly>false</ReadOnly>
    <MaxUserNameListLength>500</MaxUserNameListLength>

    <Property name="url">jdbc:postgresql://localhost/[DATABASE_NAME]</Property>
        <Property name="userName">[DATABASE_USERNAME]</Property>
        <Property name="password">[DATABASE_PASSWORD]</Property>
        <Property name="driverName">org.postgresql.Driver</Property>
    <Property name="maxActive">40</Property>
    <Property name="maxWait">60000</Property>
    <Property name="minIdle">5</Property>
</Configuration>

Step 3: JDBC Driver for PostgreSQL

Place JDBC driver for PostgreSQL inside $CARBON_HOME/repository/components/lib directory. (Tests were carried out using PostgreSQL 8.3.8 as database server & postgresql-8.4-701.jdbc3.jar as the JDBC driver)

Step 4: Starting up server for the first time

./wso2server.sh -Dsetup
