1. Download the database software and installer from the PostgreSQLdownload site and save it to your desktop. Choose the package that matches your operating system. Where available, choose the One Click Installer. These instructions assume you will use the One Click Installer. For example:
   • PostgreSQL One Click Installer for Windows.
   • PostgreSQL One Click Installer for Linux.
   • PostgreSQL One Click Installer for Mac OS X.
2. Run the installer. Please note the following information when installing PostgreSQL:
   • The password that you are prompted to provide during the installation process is for the 'postgres' account, which is the db root level account.
   • The default port for PostgreSQL is 5432. If you decide to change the default port, please ensure that your new port number does not conflict with any services running on that port. You will also need to remember to update all further mentions of db port.
   • Choose the locale that best fits your geographic location, when prompted to enter a locale.
   • Do not launch Stack Builder at the completion of the installer.
3. PostgreSQL is now installed on your machine.

1. Start the 'pgAdmin III' administration tool on your machine. The pgAdmin III administration console will display. The database user and database that will be used by Confluence are created via the 'pgAdmin III' tool.
   
   
2. Connect to the PostgreSQL server (e.g. double-click on the server name in the object browser). Enter a 'postgres' password when prompted.
   
   
   
3. Create a new user, i.e. login role (e.g. right-click click 'Login Roles' in the object browser and select 'New Login Role...'):
   
   • Enter a name and password for the new user.
   • Do not select any role privileges.
     
     
4. Create a database (e.g. right-click 'Databases' and select 'New Database...'):
   
   • Enter a name for the new database.
   • Set the owner of the database to the user you created in the previous step.
   • Select 'UTF8' for 'Encoding'.

If you are on Linux and do not have the above pgAdmin III administration tool, you can use the command line interface instead. Assuming that you are using the default installation directory of /opt/PostgreSQL/8.3/bin/, enter the following commands:

sudo -s -H -u postgres
# Create the Confluence user:
/opt/PostgreSQL/8.3/bin/createuser -S -d -r -P -E confuser
# Create the Confluence database:
/opt/PostgreSQL/8.3/bin/createdb -O confuser confluence
exit

1. Install Confluence, if you haven't done so already. Ensure that you download the Confluence distribution, not the evaluation installer.
2. Ensure that Confluence is stopped (for example, by ensuring that the application server or service which is running Confluence has been stopped or terminated).

3. Install the database drivers, if needed:

   Note: Confluence only bundles the JDBC 3 driver which will work under the 1.6 JVM. However, if you are using Java 6 and want to use the JDBC 4 driver, you can download it via Database JDBC drivers and install it as described below. You will need to remove the existing PostgreSQL JDBC 3 driver (e.g. postgresql-8.4-701.jdbc3), if you do want to use the JDBC 4 driver.

   • If you are configuring a datasource to connect to your PostgreSQL database, you will need to place the jar file in <confluence install>/WEB-INF/lib (for Confluence 2.10 onwards) or <confluence install>/common/lib (for earlier versions). Information and links to the appropriate database drivers are available on Database JDBC drivers.
     Windows renames .jar extensions to .zip! Just rename it back to .jar. You'll have to set your folder options to view hidden file extensions if you can't rename it without changing the file type (Tools >> Folder Options >> View >> Uncheck "Hide Extensions for known file types."
4. Start Confluence and after entering your license code on the 'Confluence Setup Wizard' page, click 'Custom Installation'. The 'Choose a Database Configuration' page will display.
5. Select 'PostgreSQL' and click 'External Database'. The 'Configure Database' page will display.
6. Choose your desired database connection method (please note that if you choose to connect via datasource, you will need to install the appropriate database drivers as described in the previous step).

7. Enter your PostgreSQL database setup details (as defined in the previous step above):
   

   Simply add ssl=true parameter in the Database URL, for example: jdbc:postgresql://localhost:5432/confluence?ssl=true

If the server that is hosting the PostgreSQL database is not the same server as Confluence, then please ensure that the confluence server can contact the database server and also refer to the PostgreSQL documentation on how to set up pg_hba.conf If the pg_hba.conf file is not set properly, remote communication to the PostgresSQL server will fail.

For ongoing maintenance of your server, you can continue to use PGAdmin as your SQL browser.
