Below is the SQL script for PostgreSQL that creates from scratch all the database objects. Before running it through psql, those preconditions should be met:

• The database should exist and have UTF8 encoding (createdb -E UTF8 name_of_database in shell or CREATE DATABASE name_of_database ENCODING 'UTF8' under psql)
• The plpgsql language should be enabled (createlang -d name_of_database plpgsql external command or CREATE LANGUAGE plpgsql under psql)
• The current directory should contain the SQL files that are referenced at the end of the script. These are the definitions of plpgsql functions.

This script as well as all the SQL files are available in http://www.manitou-mail.org/source/manitou-sql-0.9.10.tar.gz
