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

Description:Emit new event when a new table is added to the database. [See Docs](https://node-postgres.com/features/queries)
Version:0.0.10
Key:postgresql-new-table

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 Table",
  key: "postgresql-new-table",
  description: "Emit new event when a new table is added to the database. [See Docs](https://node-postgres.com/features/queries)",
  version: "0.0.10",
  type: "source",
  props: {
    ...common.props,
    schema: {
      propDefinition: [
        common.props.postgresql,
        "schema",
        (c) => ({
          rejectUnauthorized: c.rejectUnauthorized,
        }),
      ],
    },
  },
  async run() {
    const previousTables = this._getPreviousValues() || [];

    const tables = await this.postgresql.getTables(this.schema, this.rejectUnauthorized);

    const newTables = tables.filter((table) => !previousTables.includes(table));
    for (const table of newTables) {
      const meta = this.generateMeta(table);
      this.$emit(table, meta);
    }

    this._setPreviousValues(tables);
  },
};

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.
LabelPropTypeDescription
PostgreSQLpostgresqlappThis component uses the PostgreSQL app.
N/Adb$.service.dbThis component uses $.service.db to maintain state between executions.
Polling Intervaltimer$.interface.timer

Pipedream will poll the API on this schedule

Reject UnauthorizedrejectUnauthorizedboolean

If true, the server certificate is verified against the list of supplied CAs. If you encounter the error Connection terminated unexpectedly, try setting this prop to false.

SchemaschemastringSelect 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:

  1. Accessible from the public internet (You may need to add a firewall rule on 0.0.0.0/0 on port 5432), or

  2. 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: 5432, 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

About PostgreSQL

PostgreSQL is a free and open-source relational database management system emphasizing extensibility and SQL compliance.
