我已经从源代码安装了postgresql-9.2.4，现在在rails应用程序中执行:
我得到rake db:create个命令:
$ bin/rake db:create RAILS_ENV="test"
PG::Error: ERROR: 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.
: CREATE DATABASE "verticals_test" ENCODING = 'unicode'
/home/vagrant/my-project/.gems/ruby/1.9.1/gems/activerecord-3.2.12/lib/active_record/connection_adapters/postgresql_adapter.rb:652:in `exec
....
bin/rake:16:in `load'
bin/rake:16:in `<main>'
Couldn't create database for {"adapter"=>"postgresql", "encoding"=>"unicode", "database"=>"my_db", "host"=>"localhost", "pool"=>5, "username"=>"my_user", "password"=>"my_password"}
知道吗？
