为在 PostgreSQL 中创建数据库和地理数据库 (geodatabase) 编写脚本

您可以复制并修改下方所提供的示例脚本之一。其中一个脚本是在 PostgreSQL 数据库群集中同时创建数据库和地理数据库。另外一个脚本则在现有预配置 PostgreSQL 数据库中创建地理数据库。

在运行脚本之前必须完成一些附加任务。以下步骤对这些任务和脚本自身进行了介绍：

步骤:

1. 在服务器上安装并配置 PostgreSQL。
2. 修改 pg_hba.conf 文件以允许连接到数据库群集。
3. 创建目录和表空间以存储您的 PostgreSQL 数据库。
4. 如果要从安装有 PostgreSQL 的服务器以外的其他计算机上运行 Python 脚本，请在将要运行 Python 脚本的计算机上安装 PostgreSQL libpq 客户端。

   PostgreSQL 客户端文件可从 Esri 客户关怀中心门户网站下载。如果从 ArcGIS 32 位客户端运行此脚本，则需下载 32 位 PostgreSQL 客户端文件。如果要从 ArcGIS for Server 运行脚本，则需下载 64 位的 PostgreSQL 客户端文件。有关详细信息，请参阅设置到 PostgreSQL 的连接。

5. 在安装了 ArcGIS for Desktop（标准版 或 高级版）、ArcGIS for Server Enterprise（Standard 或 Advanced）或具有 Geodatabase Update 扩展模块的 ArcGIS Engine 的计算机上，将这些示例脚本之一复制到 ArcGIS for Desktop 的 Python 窗口或复制到任何 Python IDE（如 PythonWin 或 WING）中。

   此示例将创建 sde 用户和方案、授予 sde 用户创建地理数据库的权限、指定存储数据库的表空间、创建数据库，然后创建地理数据库。

6. 修改此脚本以包含特定于您的站点的信息。
7. 运行您复制和更改的脚本。

用于地理数据库创建的日志文件 (GDBCreateGeodatabase<#>.log) 会写入运行此脚本的计算机上 TEMP 或 TMP 变量所指定的目录。
