+
+  The default version of PostgreSQL has been switched from 9.3 to 9.5.
+  The upgrade procedure can use up twice the space the databases
+  currently needs. If you have a big amount of stored data take a
+  closer look at the manpage of pg_upgrade for avoidance and/or
+  speedup of the upgrade.
+
+  The upgrade instructions consider a basic usage and do not match
+  complex scenarious like replication, sharding or similar.
+  
+  Upgrade instructions:
+
+  First stop your PostgreSQL, create PostgreSQL-binaries and backup your data.
+  If you have another Version of PostgreSQL installed, for example 9.3.12, your
+  files are named accourding to this.
+  
+  # service postgresql stop
+  # pkg create postgresql93-server postgresql93-contrib
+  # mkdir /tmp/pg-upgrade
+  # tar xf postgresql93-server-9.3.17.txz -C /tmp/pg-upgrade
+  # tar xf postgresql93-contrib-9.3.17.txz -C /tmp/pg-upgrade
+  # mv /usr/local/pgsql/data /usr/local/pgsql/data93
+  # pkg delete -f databases/postgresql93-server databases/postgresql93-contrib databases/postgresql93-client
+
+  Now update PostgreSQL:
+
+    pkg user:
+    # pkg install databases/postgresql95-server databases/postgresql95-contrib
+    # pkg upgrade
+
+    Portmaster users:
+    # portmaster databases/postgresql95-server databases/postgresql95-contrib
+    # portmaster -a
+
+    Portupgrade users:
+    # portinstall databases/postgresql95-server databases/postgresql95-contrib
+    # portupgrade -a
+
+  After installing the new PostgreSQL version you need to convert
+  all your databases to new version:
+  
+  # service postgresql initdb
+  # su -l pgsql -c "pg_upgrade -b /tmp/pg-upgrade/usr/local/bin/ -d /usr/local/pgsql/data93/ -B /usr/local/bin/ -D /usr/local/pgsql/data/"
+
+  Now the migration is finished. You can start PostgreSQL again with:
+
+  # service postgresql start
+
