Getting Started#

This integration creates a workflow with a PostgreSQL trigger and HTTP / Webhook action. When you configure and deploy the workflow, it will run on Pipedream's servers 24x7 for free.

Select this integration
Configure the New Column trigger
1. Connect your PostgreSQL account
2. Configure Polling Interval
3. Configure Reject Unauthorized
4. Select a Schema
5. Select a Table
Configure the Send any HTTP Request action
1. Connect your HTTP / Webhook account
2. Configure HTTP Request Configuration
3. Optional- Configure Include Response Headers
Deploy the workflow
Send a test event to validate your setup
Turn on the trigger

Details#

This integration uses pre-built, source-available components from Pipedream's GitHub repo. These components are developed by Pipedream and the community, and verified and maintained by Pipedream.

To contribute an update to an existing component or create a new component, create a PR on GitHub. If you're new to Pipedream component development, you can start with quickstarts for trigger span and action development, and then review the component API reference.

Trigger#

New Column on PostgreSQL

Description:Emit new event when a new column is added to a table. [See Docs](https://node-postgres.com/features/queries)

Version:0.0.7

PostgreSQL Overview#

Assuming you want a few paragraphs on what you can do with the PostgreSQL API:

The following examples demonstrate some of the things that can be done with the
PostgreSQL API:

Developing a custom storage engine for PostgreSQL
Adding a new data type to PostgreSQL
Creating a new function for PostgreSQL
Building a graphical user interface for PostgreSQL
And much more!

Trigger Code#

import common from "../common.mjs";

export default {
  ...common,
  name: "New Column",
  key: "postgresql-new-column",
  description: "Emit new event when a new column is added to a table. [See Docs](https://node-postgres.com/features/queries)",
  version: "0.0.7",
  type: "source",
  props: {
    ...common.props,
    schema: {
      propDefinition: [
        common.props.postgresql,
        "schema",
        (c) => ({
          rejectUnauthorized: c.rejectUnauthorized,
        }),
      ],
    },
    table: {
      propDefinition: [
        common.props.postgresql,
        "table",
        (c) => ({
          schema: c.schema,
          rejectUnauthorized: c.rejectUnauthorized,
        }),
      ],
    },
  },
  async run() {
    const previousColumns = this._getPreviousValues() || [];

    const columns = await this.postgresql
      .getColumns(this.table, this.schema, this.rejectUnauthorized);

    const newColumns = columns.filter((column) => !previousColumns.includes(column));
    for (const column of newColumns) {
      const meta = this.generateMeta(column);
      this.$emit(column, meta);
    }

    this._setPreviousValues(columns);
  },
};

Trigger Configuration#

This component may be configured based on the props defined in the component code. Pipedream automatically prompts for input values in the UI and CLI.

Label	Prop	Type	Description
PostgreSQL	`postgresql`	`app`	This component uses the PostgreSQL app.
N/A	`db`	`$.service.db`	This component uses `$.service.db` to maintain state between executions.
Polling Interval	`timer`	`$.interface.timer`	Pipedream will poll the API on this schedule
Reject Unauthorized	`rejectUnauthorized`	`boolean`	If not false, the server certificate is verified against the list of supplied CAs. If you get the error `Connection terminated unexpectedly` try to set this prop as `false`
Schema	`schema`	`string`	Select a value from the drop down menu.
Table	`table`	`string`	Select a value from the drop down menu.

Trigger Authentication#

PostgreSQL uses API keys for authentication. When you connect your PostgreSQL account, Pipedream securely stores the keys so you can easily authenticate to PostgreSQL APIs in both code and no-code steps.

Before you connect to your PostgreSQL database from Pipedream, please make sure your database is either:

Accessible from the public internet (You may need to add a firewall rule on 0.0.0.0/0 on port 3306), or
Accessible from an SSH server that you route PostgreSQL requests through

After that, enter the following values:

host: The hostname or IP address of your PostgreSQL server
port: 3306, unless you run PostgreSQL on a different port
username: The account username to log in
password: The account password to log in
database: The name of the PostgreSQL database to run queries against
