Can Postgres connect with QuestDB?

Yes, Postgres can connect with QuestDB using n8n.io. With n8n, you can create workflows that automate tasks and transfer data between Postgres and QuestDB. Configure nodes for Postgres and QuestDB in the n8n interface, specifying actions and triggers to set up their connection.

Can I use Postgres’s API with n8n?

Yes, with n8n, you can programmatically interact with Postgres’s API via pre-defined supported actions or raw HTTP requests. With the HTTP Request node, you create a REST API call. You need to understand basic API terminology and concepts.

Can I use QuestDB’s API with n8n?

Yes, with n8n, you can programmatically interact with QuestDB’s API via pre-defined supported actions or raw HTTP requests. With the HTTP Request node, you create a REST API call. You need to understand basic API terminology and concepts.

Is n8n secure for integrating Postgres and QuestDB?

Yes, it is safe to use n8n to integrate Postgres and QuestDB. n8n offers various features to ensure the safe handling of your data. These include encrypted data transfers, secure credential storage, RBAC functionality, and compliance with industry-standard security practices (SOC2 compliant). For hosted plans, data is stored within the EU on servers located in Frankfurt, Germany. You can also host it on your own infrastructure for added control. Learn more about n8n’s security practices here.

How to get started with Postgres and QuestDB integration in n8n.io?

To start integrating Postgres and QuestDB in n8n, you have different options depending on how you intend to use it: n8n Cloud: hosted solution, no need to install anything. Self-host: recommended method for full-control or customized use cases. Unlike other platforms that charge per operation, step, or task, n8n charges only for full workflow executions. This approach guarantees predictable costs and scalability, no matter the complexity or volume of your workflows.

How to connect Postgres and QuestDB

Step 1: Create a new workflow
Step 2: Add and configure nodes
Step 3: Connect
Step 4: Customize and extend your integration
Step 5: Test and activate your workflow

Step 1: Create a new workflow and add the first step

In n8n, click the "Add workflow" button in the Workflows tab to create a new workflow. Add the starting point – a trigger on when your workflow should run: an app event, a schedule, a webhook call, another workflow, an AI chat, or a manual trigger. Sometimes, the HTTP Request node might already serve as your starting point.

Step 2: Add and configure Postgres and QuestDB nodes

You can find Postgres and QuestDB in the nodes panel. Drag them onto your workflow canvas, selecting their actions. Click each node, choose a credential, and authenticate to grant n8n access. Configure Postgres and QuestDB nodes one by one: input data on the left, parameters in the middle, and output data on the right.

Step 3: Connect Postgres and QuestDB

A connection establishes a link between Postgres and QuestDB (or vice versa) to route data through the workflow. Data flows from the output of one node to the input of another. You can have single or multiple connections for each node.

Step 4: Customize and extend your Postgres and QuestDB integration

Use n8n's core nodes such as If, Split Out, Merge, and others to transform and manipulate data. Write custom JavaScript or Python in the Code node and run it as a step in your workflow. Connect Postgres and QuestDB with any of n8n’s 1000+ integrations, and incorporate advanced AI logic into your workflows.

Step 5: Test and activate your Postgres and QuestDB workflow

Save and run the workflow to see if everything works as expected. Based on your configuration, data should flow from Postgres to QuestDB or vice versa. Easily debug your workflow: you can check past executions to isolate and fix the mistake. Once you've tested everything, make sure to save your workflow and activate it.
