Airtable PostgreSQL Integration: How to Transfer and Sync Data Efficiently?

Airtable is a user-friendly, spreadsheet-like database that enables teams to organize and manage data efficiently, while PostgreSQL is a robust relational database known for its scalability and advanced features. Integrating Airtable PostgreSQL allows users to leverage Airtable’s flexibility while benefiting from PostgreSQL’s robustness for data storage and analytics. This blog explores how to connect Airtable to PostgreSQL manually using CSV, best practices for syncing, key use cases, and how PostgreSQL arrays can enhance data management. Whether you want to migrate data or maintain a live sync, this guide will help you get started.

Overview of Airtable

Airtable is a web application that allows you to create various spreadsheets without writing code. You can seamlessly organize your data into tables by dragging and dropping rows and columns. Read about building airtable dashboards to get insights from the data stored in Airtable. Moreover, Airtable offers multiple features like file storage, document management, task lists, calendar views, and much more that allow you to generate engaging spreadsheets.

Overview of PostgreSQL

PostgreSQL is a popular object-relational database management system that offers enterprise-grade features with a strong focus on extensibility. It runs on all major operating systems, such as Unix and Windows. It is open-source, fully ACID-compliant, and supports foreign keys, joins, etc., in multiple languages. It is available in cloud-based deployments by most major cloud providers. Loading data from Facebook Ads to PostgreSQL will give you the power of SQL to slice and dice your advertising data to unearth actionable insights.

Steps To Setup Airtable PostgreSQL Integration

Step 1. Export Data from Airtable

Since Airtable doesn’t offer a built-in export to PostgreSQL, you need to export data as CSV:

• Open your Airtable base.
• Go to the Table you want to export.
• Click on View options → Download CSV.

• Save the CSV file.

Step 2. Prepare Your PostgreSQL Database

Before importing, make sure you have a PostgreSQL database set up.

• Create a Table in PostgreSQL: You need a table that matches the structure of your Airtable data.

CREATE TABLE airtable_data (
    id SERIAL PRIMARY KEY
    column1 TEXT,
    column2 TEXT,
    column3 INT
);

Step 3. Import CSV Data into PostgreSQL

There are two methods to import the CSV into PostgreSQL:

Method 1: Using COPY Command 

1. Move the CSV file to the PostgreSQL server.
2. Run the following command in psql:

COPY airtable_data(column1, column2, column3)
FROM '/path/to/your/file.csv'
DELIMITER ','
CSV HEADER;

Method 2: Using pgAdmin (GUI Approach)

• Open pgAdmin and connect to your database.
• Go to the table → Right-click → Import/Export Data.

Best Practices for Syncing Airtable With Postgres

• Optimize data mapping: Ensure your data mappings are accurate and optimized to reduce the possibilities of errors and improve sync performance.
• Schedule syncs during off-peak hours: If using a batch process, schedule your sync processes during periods of low database usage. This will minimize the impact on performance.
• Regularly monitor and optimize database performance: Monitor your database performance metrics and make adjustments as needed to ensure optimal operation.
• Data security and privacy: Use strong authentication methods and credentials for both Airtable and Postgres. This will prevent unauthorized access. Also,regularly review user access and permissions in both Airtable and Postgres to limit potential data breaches.
• Handling schema changes: Before making schema changes in either Airtable or Postgres, pause the sync process to prevent errors or data corruption.To reflect the schema changes update your data mappings and configurations in your third-party tools or custom scripts.

Use Cases of Airtable PostgreSQL Integration

• Consolidating data: Airtable to Postgres integration enables you to consolidate data from different sources. This improves the efficiency of data analysis and reporting.
• Data migration: This integration helps you to migrate your data without losing valuable information.
• Real-time analytics: you can run real-time analytics and generate up-to-date reports and visualizations based on the latest information through Airtable PostgreSQL integration.

Airtable and PostgreSQL Arrays

1. Before moving towards dealing with practical problems, it is important to know about Postgres arrays a bit in detail as they provide all the functionalities to work with. 
2. Typically, arrays in PostgreSQL Tables are delimited with curly braces {}, instead of [].
3. The Lookup Field provides the connectivity between different parameters of the database as shown in the below figure in the form of Product Inventory. 

The following query can help in selecting some columns.

SELECT product_inventory_updated FROM warehouse_locations_updated;

The product_Inventory comes out to be as One Column as shown below.

While setting up Airtable PostgreSQL Integration, fields can contain multiple values and we can extract the values one by one that helps in making the extraction process simple. Some of these queries are given below:

1) Unnest()

The unnest() functionality allows one to un-nest each item of an array onto its own or a separate row. For example, if one wants to see which employee works for more than 8 hours and is performing his duties well, he can simply pull the list of all employees and their working hours. To get this data, a simple query needed to be written is:

SELECT employees FROM HR_data WHERE working_hours::integer > 8;

2) ANY

ANY can be used to check if any specific quality needs to be checked in any employee, for example, hard-working nature, punctuality, etc. This is shown below.

SELECT Employee[1]
FROM HR_data
WHERE 'quality' = ANY(punctuality);

3) JOINS

JOIN is one of the most important functions offered by PostgreSQL with the database. 

It would be nice to see how many employees are in each branch of the office. Airtable lookup can help out in giving answers to this question but will not let you know exactly what you want. Moreover, in Airtable it will not be a simple process so one can leverage the functionality that PostgreSQL offers with the help of Join functionality. 

Let’s use ANY with a JOIN to see how many employees are in each office:

SELECT
    Office_locations.name AS "Office",
    SUM((employees.numbers_present[1]::INTEGER) 
FROM office_location
JOIN office_employees
    ON EMployee_employee.id = ANY (office_location.employee_number)
GROUP BY office_locations.name
ORDER BY office_locations.name ASC;

Benefits of using Airtable & PostgreSQL Arrays

1. Airtable provides a very user-friendly interface and makes it possible for users to add or create new tables, change or edit any existing columns and delete the columns if needed. 
2. To consider, let’s say we have an Employees table with a column that contains the employee’s Photo ID. If more Photo IDs are needed, we just need to drag another image and replace the existing one.
3. There is no need to migrate the columns or delete previous columns, etc. It is that simple.  
4. This flexibility can be used easily to pull data out of Airtable into PostgreSQL with the help of Airtable API.
5. The pulled data is represented as PostgreSQL Arrays. Therefore, if any image is added, PostgreSQL tables provide the flexibility to support it without one to perform any migrations, changes in existing queries, or anything else. 
6. Airtable API helps in containing multiple values including lookups, collaborators, multiple select & attachments, and all these field types are represented in PostgreSQL as the arrays which are first-class in PostgreSQL.
