Source Connector for PostgreSQL¶

This guide describes how to configure digna to connect to Postgres using either the native Python connector or the ODBC driver.

It refers to the screen "Create a Database Connection".

Native Python Driver¶

Library: psycopg
Supported Authentication: Password-based authentication only

⚠️ For other authentication methods, please use the ODBC driver.

digna Configuration (Native Driver)¶

Provide the following information in the "Create a Database Connection" screen:

Technology:      Postgres
Host Address:    Server name or IP address
Host Port:       Port number, e.g. 5432
Database Name:   Database name
Schema Name:     Schema that contains the source data
User Name:       Database user name
User Password:   Password for the user
Use ODBC:        Disabled (default)

ODBC Driver¶

The ODBC driver may support a broader range of authentication and connectivity options. This section focuses on password-based authentication using the driver PostgreSQL Unicode(x64).

1. Install the ODBC Driver¶

Install the PostgreSQL Unicode(x64) (or similar) by following the vendor’s official installation guide.

2. Configure the ODBC Data Source¶

Follow these steps to configure a new ODBC data source using password-based authentication:

Step 1¶

Note: If your database setup requires you to choose a specific "SSLMode", please make sure to also use this when defining a DSN-less configuration.

Step 2 – Test the connection¶

Click the Test Connection button.

Now you can configure digna to use the ODBC connection, either with a DSN (Data Source Name) or a DSN-less setup.

A. DSN-Based Configuration¶

digna Configuration¶

In the "Create a Database Connection" screen, provide the following:

Technology:      PostgreSQL
Database Name:   Database that contains the source schema
Schema Name:     Schema that contains the source data
Use ODBC:        Enabled

ODBC Properties¶

name: "DSN",    value: "PostgreSQL35W"

🔹 The DSN must match the name defined in your ODBC driver configuration.

B. DSN-less Configuration¶

digna Configuration¶

In the "Create a Database Connection" screen, provide the following:

Technology:      PostgreSQL
Database Name:   Schema that contains the source data (same as Schema Name)
Schema Name:     Schema that contains the source data
Use ODBC:        Enabled

ODBC Properties¶

name: "DRIVER",     value: "PostgreSQL Unicode(x64)"
name: "SERVER",     value: "your server name or IP address"
name: "PORT",       value: "5432"
name: "DATABASE",   value: "postgres or other name of your database"
name: "UID",        value: "your postgres user'
name: "PWD",        value: "your postgres password"
name: "SSLMode",    value: "require"
