Below is the SQL script for PostgreSQL that creates from scratch all the database objects. Before running it through psql, 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). Also, the current directory should contain the SQL files that are referenced at the end of the script; they contain 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-0.9.11.tar.gz
