创建Odoo8数据库时的“new encoding (UTF8) is incompatible with the encoding of the template database (SQL_ASCII)“问题

Odoo8创建数据库时，显示如下错误信息：

DataError: new encoding (UTF8) is incompatible with the encoding of the template database (SQL_ASCII)
HINT:  Use the same encoding as in the template database, or use template0 as template.

解决方法：

1. First, we need to drop template1. Templates can’t be dropped, so we first modify it so t’s an ordinary database:

   UPDATE pg_database SET datistemplate = FALSE WHERE datname = 'template1';

2. Now we can drop it:

   DROP DATABASE template1;

3. Now its time to create database from template0, with a new default encoding:

   CREATE DATABASE template1 WITH TEMPLATE = template0 ENCODING = 'UNICODE';

4. Now modify template1 so it’s actually a template:

   UPDATE pg_database SET datistemplate = TRUE WHERE datname = 'template1';

5. Now switch to template1 and VACUUM FREEZE the template:

   \c template1

   VACUUM FREEZE;

Problem should be resolved.
