 =head2 Creating the database

+The default settings file (C<conf/general.yml>) assumes the database is called fms and the user the same.
 You can change these if you like.
 
+If you wish to create this new database and database user with
+password authentication, the following steps may help.  First, create
+the fms user:
 
+    $ sudo -u postgres createuser fms
+    Shall the new role be a superuser? (y/n) n
+    Shall the new role be allowed to create databases? (y/n) n
+    Shall the new role be allowed to create more new roles? (y/n) n
 
+Then create the fms database:
+
+    $ sudo -u postgres createdb fms
+
+Set the password of the fms user, and change the owner of the fms database to be the fms user:
+
+    $ sudo -u postgres psql
+    postgres=# ALTER USER fms WITH PASSWORD 'somepassword'
+    ALTER ROLE
+    postgres=# ALTER DATABASE fms OWNER to fms;
+    ALTER DATABASE
+    postgres=# \q
+    $
+
+Then you need to configure PostgreSQL to allow password-based access
+to the fms database as the user fms from using Unix-domain sockets.
+Edit the file C</etc/postgresql/8.4/main/pg_hba.conf> and add as the
+first line:
+
+    local   fms     fms     md5
+
+You will then need to restart PostgreSQL with:
+
+    $ sudo /etc/init.d/postgresql restart
+
+If you want to access the database from the command line, you can add
+the following line to C<~/.pgpass>:
+
+    localhost:*:fms:fms:somepassword
+
+Then you should be able to access the database with:
+
+    $ psql -U fms fms
 
 =head2 Set up the database
 
-Once you've created the database you can use the sql in C<db/schema.sql> to create the required
+Before creating the database schema, you will need to install the
+PostgreSQL's SQL procedural language into the database:
+
+    createlang -U fms plpgsql fms
+
+Now you can use the sql in C<db/schema.sql> to create the required
 tables, triggers and stored procedures. You will also need to run
-C<db/alert_types.sql> which
-populates the alert_types table.
+C<db/alert_types.sql> which populates the alert_types table.  For
+example, you might run:
+
+    $ psql -U fms fms < db/schema.sql
+    ...
+    $ psql -U fms fms < db/alert_types.sql
+    ...
