PostgreSQL Installation

Follow these instuctions:

• Download and install PostgreSQL (http://www.postgresql.org/)
• Download appropriate Postgres JDBC driver (or directly from the Maven Central Repository and copy the JAR into your container's common lib directory or in the XWiki webapp (in WEB-INF/lib)
• Start PostgreSQL
• Create the xwiki user (pick any password you want), and the xwiki database:
  # psql -U <replace_with_your_admin_user_eg_postgres>;
  
  // 1. create a database
  CREATE DATABASE xwiki
  WITH OWNER = <replace_with_your_admin_user_eg_postgres>
  ENCODING = 'UNICODE'
  TABLESPACE = pg_default;
  
  // Verify available databases
  \l
  
  // connect to xwiki
  \connect xwiki
  
  // 2. create a user xwiki
  CREATE USER xwiki PASSWORD 'xwiki' VALID UNTIL 'infinity';
  
  // Verify available users
  \du
  
  // 3. grant access to the database for the group xwiki
  GRANT ALL ON SCHEMA public TO xwiki;

  Another way, if you have 'createuser' and 'createdb' programs in your $PATH and postgres is admin user for PostgreSQL (this is by default in PostgreSQL installation on Linux):

  # createuser xwiki -S -D -R -P -Upostgres
  ## enter password, ie: 'xwiki'
  # createdb xwiki -Eunicode -Oxwiki -Upostgres
• Tell XWiki to use Oracle. To do this, edit the WEB-INF/hibernate.cfg.xml file where you have expanded the XWiki WAR file and uncomment the PostgreSQL part. Make sure to review the connection.url property. For example a typical value would be:
  <property name="connection.url">jdbc:postgresql://localhost:5432/xwiki</property>
