 The option `-P` (for password prompt), will encrypt the password with the
 method set in the configuration file :file:`pg_hba.conf`.  If you do not use this
 option `-P`, then the default value will be null and you will need to set it
 with::
 
-  $ su postgres -c "echo ALTER USER username WITH PASSWORD 'userpasswd' | psql"

 The above login/password will be requested when you will create an instance with
 `cubicweb-ctl create` to initialize the database of your instance.

+Database creation
++++++++++++++++++
+
+If you create the database by hand (instead of using the `cubicweb-ctl
+db-create` tool), you may want to make sure that the local settings are
+properly set. For example, if you need to handle french accents
+properly for indexing and sorting, you may need to create the database
+with something like::
+
+  $ createdb --encoding=UTF-8 --locale=fr_FR.UTF-8 -t template0 -O <owner> <dbname>
+
 Notice that the `cubicweb-ctl db-create` does database initialization that
 may requires a postgres superuser. That's why a login/password is explicitly asked
 at this step, so you can use there a superuser without using this user when running
 the instance. Things that require special privileges at this step:
 
 * database creation, require the 'create database' permission
-* install the plpython extension language (require superuser)
-* install the tsearch extension for postgres version prior to 8.3 (require superuser)
+* install the `plpython` extension language (require superuser)
 
 To avoid using a super user each time you create an install, a nice trick is to
 install plpython (and tsearch when needed) on the special `template1` database,
 so they will be installed automatically when cubicweb databases are created
