PostgreSQL Connector

Domo University
  • Updated

Intro

PostgreSQL is a widely used open-source relational database management system. You can use Domo's PostgreSQL Connector to pull data from your PostgreSQL database and compile custom reports. You indicate the data you want by inputting an SQL query. For more information about the PostgreSQL API, visit their website. ( https://www.postgresql.org/docs/ )

The PostgreSQL connector is a "Database" connector, meaning it retrieves data from databases using a query. In the Data Center, you can access the connector page for this and other Database connectors by clicking Database in the toolbar at the top of the window.

You connect to your PostgreSQL database in the Data Center. This topic discusses the fields and menus that are specific to the PostgreSQL connector user interface. General information for adding DataSets, setting update schedules, and editing DataSet information is discussed in Adding a DataSet Using a Data Connector.

Note: Depending on your network's structure, your IT administrator may need to whitelist any IP addresses necessary for the data connector to retrieve data. Contact your IT administrator for assistance.

Best Practices

  • Use read-only queries only.

  • Use "Replace" instead of "Append."

Prerequisites

To connect to a PostgreSQL database and create a DataSet, you must have the following:

  • The username and password you use to log into your PostgreSQL database

  • The host name for the database

  • The port number for the database

  • The database name

CA certificate text or URL path is required only if you select Certificate text or URL path, respectively, in the Certificate type menu.

Before you can connect to a PostgreSQL database, you must also whitelist a number of IP addresses on your database server on the port you want to connect to. For the full list of IP addresses, see Whitelisting IP Addresses for Connectors.

Connecting to Your PostgreSQL Database

This section enumerates the options in the Credentials and Details panes in the PostgreSQL Connector page. The components of the other panes in this page, Scheduling and Name & Describe Your DataSet, are universal across most connector types and are discussed in greater length in Adding a DataSet Using a Data Connector.

Credentials Pane

This pane contains fields for entering credentials to connect to your database. The following table describes what is needed for each field:  

Field

Description

Username

Enter your PostgreSQL username.

Password

Enter your PostgreSQL password.

Host

Enter the host name for the SQL database. For example: db.company.com

Port

Enter the port number for the database.

Certificate

Paste the text for your CA certificate or enter the URL where your certificate is located. This is optional. If you do not want to include a certificate, select No certificate in the Certificate Type menu.

Certificate Type 

Select a certificate type. If you do not want to include a certificate, select No certificate. If you select Certificate text, you must paste the text for your certificate in the Certificate field. If you select URL path, you must enter the URL where your certificate is located in the Certificate field.   

Database

Enter the name of the SQL database.

Once you have entered valid PostgreSQL credentials, you can use the same account any time you go to create a new PostgreSQL DataSet. You can manage connector accounts in the Accounts tab in the Data Center. For more information about this tab, see Managing User Accounts for Connectors.

Details Pane

In this pane you create an SQL query to pull data from your database.

Menu

Description

SQL Query

Enter the Structured Query Language (SQL) query to use in selecting the data you want. For example:

select * from Employee

Fetch Size 

Enter a fetch size for memory performance. If you leave this blank, a default size of 10,000 is used. If an "Out of memory" message appears, decrease the fetch size. 

 

 

Other Panes

For information about the remaining sections of the connector interface, including how to configure scheduling, retry, and update options, see Adding a DataSet Using a Data Connector.

Troubleshooting

  • Make sure the appropriate IP addresses are whitelisted (see Prerequisites for a list of IP addresses).

  • Try decreasing fetch size or leave it empty.
