我在 Windows 上，安装了 32 位的 python 2.6.6 和 psycopg2。

当 psycopg2 尝试连接时，它会得到OperationalError：

Python 2.6.6 (r266:84297, Aug 24 2010, 18:46:32) [MSC v.1500 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import psycopg2
>>> conn = psycopg2.connect("dbname=your_database user=postgres password=xxxx host=127.0.0.1:5432")
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Python26\lib\site-packages\psycopg2\__init__.py", line 164, in connect
    conn = _connect(dsn, connection_factory=connection_factory, async=async)
psycopg2.OperationalError: could not translate host name "127.0.0.1:5432" to address: Unknown server error

我可以使用 pgAdmin3 连接到 PostgreSQL 实例127.0.0.1:5432。

任何想法？

:5432从host名称中删除端口对我有用。
