ArcGIS Help 10.1 - Scripting database and geodatabase creation in PostgreSQL

You can copy and alter one of the example scripts provided. One creates both a database and geodatabase in a PostgreSQL database cluster. The other creates a geodatabase in an existing, preconfigured PostgreSQL database.

There are additional tasks you must complete before running the script. Those tasks and the script itself are described in the following steps:

Steps:

Install and configure PostgreSQL on your server.
Alter the pg_hba.conf file to allow connection to the database cluster.
Create a directory and tablespace to store your PostgreSQL database.
If you will be running the Python script from a different computer than the server where PostgreSQL is installed, install the PostgreSQL libpq client on the computer from which you will run the Python script.
The PostgreSQL client files can be downloaded from the Esri Customer Care Portal. If you will be running the script from an ArcGIS 32-bit client, download the 32-bit PostgreSQL client files. If you will be running the script from ArcGIS for Server, download the 64-bit PostgreSQL client files. See Setting up a connection to PostgreSQL for more information.

Copy one of these example scripts to the Python window in ArcGIS for Desktop or to any Python IDE, such as PythonWin or WING, on a computer where ArcGIS for Desktop (Standard or Advanced), ArcGIS for Server Enterprise (Standard or Advanced), or ArcGIS Engine with the Geodatabase Update extension is installed.

This example creates an sde user and schema, grants the sde user privileges to create a geodatabase, specifies a tablespace to store the database, creates a database, then creates the geodatabase.

Run the script you copied and altered.

A log file for the geodatabase creation (GDBCreateGeodatabase<#>.log) is written to the directory specified for your TEMP or TMP variable on the computer where the script is run.
