What is PostgreSQL?

PostgreSQL is a powerful open-source relational database used to store and query structured data for applications, analytics, and internal systems. By connecting PostgreSQL to Konnectify, you can turn database events (like new rows) into automated workflows and run parameterized queries/functions as part of end-to-end integrations.

This is especially useful when PostgreSQL is your system of record and you need to sync data to other tools, enrich records, or generate downstream actions whenever new data appears.

New to PostgreSQL?

Get PostgreSQL running locally or in the cloud, then create a database and user with access to the tables you want to automate.

New to Konnectify?

Build workflows with triggers and actions, map fields, test runs, and go live—without managing infrastructure.

What you can automate

•Trigger workflows when new rows are added to a table

•Poll using a cursor to safely process only new/changed results

•Execute parameterized SELECT queries using placeholders

•Fetch a single matching row for lookups and enrichment

•Fetch multiple rows for reporting or batch-style downstream steps

•Call stored PostgreSQL functions for business logic and transformations

API & authentication

Authentication method: Database credentials

This connector authenticates using your PostgreSQL host, port, database name, and a username/password. Konnectify uses these credentials only to connect and run the trigger polling queries and action queries/functions you configure.

What the PostgreSQL connector can do

Poll a table for new rows using cursor-based tracking.
Poll with a custom SELECT query using cursor-based tracking.
Execute a custom SELECT query and return one matching row.
Execute a custom SELECT query and return all matching rows.
Execute a stored PostgreSQL function.

Important: permissions, performance & limits

Ensure the database user has only the minimum required permissions (recommended: read-only for query-only workflows).
Polling frequency and query complexity affect load on your database. Use indexes and cursor columns (like an incrementing ID or timestamp).
Some managed PostgreSQL providers impose connection limits and query timeouts. If you see intermittent failures, check provider limits and scale accordingly.

How to connect

Prerequisites

A reachable PostgreSQL host (publicly accessible or via your network/VPN as applicable).
Port (commonly 5432).
Database name.
Database user and password with required permissions.
SSL/TLS requirements as configured by your database provider (if applicable).

Add PostgreSQL to a Workflow

Open your Konnectify workspace and create (or open) a Workflow.
Click Add step and select PostgreSQL from the apps list.

Authorize via database credentials

Enter your PostgreSQL Host, Port, Database Name, Username, and Password.
Save the connection. Konnectify will validate connectivity when possible.

Configure the Trigger or Action

Select the Trigger (e.g., New Row) or an Action (e.g., Execute Query).
Provide the required query/table/function fields and map any dynamic inputs.
For query actions, use {{placeholder}} syntax for dynamic values coming from earlier steps.

Tip for safe query configuration

Prefer indexed cursor columns for polling (e.g., an increasing ID or created_at timestamp).
Avoid long-running queries in triggers; keep polling lightweight to prevent timeouts and reduce DB load.

Test the Workflow

Run a test to confirm the connection and validate your query results.
If using a polling trigger, insert a new test row and confirm the trigger picks it up.

Activate the Workflow

Turn on the Workflow.
Monitor initial runs and adjust polling/query settings if needed.

Triggers 2

PostgreSQL triggers in Konnectify are poll-based. Konnectify periodically runs your configured table/query and uses cursor-based tracking to identify new results without reprocessing older rows.

Database Queries 2 triggers

New Row

Polls PostgreSQL using a cursor-based for rows in a table.

Custom Query

Polls PostgreSQL using a cursor-based custom SELECT query.

Actions 3

Use actions to run parameterized queries (single-row or multi-row results) and to execute stored PostgreSQL functions as part of your workflow.

Database Queries 2 actions

Execute Query (Returns one matching row)

Executes a custom SELECT query. Use {{placeholder}} for dynamic inputs.

Execute Query (returns all matching rows)

Executes a custom SELECT query. Use {{placeholder}} for dynamic inputs.

Functions 1 actions

Execute PostgreSQL Function

Execute a stored PostgreSQL function

Popular automations

Examples of common PostgreSQL workflows you can build with the available triggers and actions.

Enrich new records with lookup data

When a new row is inserted, run a single-row query to fetch related details (e.g., user profile, account info) and pass it downstream.

New Row → Execute Query (Returns one matching row)

Build a scheduled export/report workflow

Poll with a custom query to find newly eligible rows, then fetch all matching rows for a consolidated report step.

Custom Query → Execute Query (returns all matching rows)

Run business logic using a stored function

When a new row arrives, call a PostgreSQL function to compute derived fields, validate data, or generate normalized outputs.

New Row → Execute PostgreSQL Function

Detect duplicates or conflicts early

Poll for new candidate rows and immediately query for an existing match (by email, external_id, etc.) so you can branch logic in later steps.

Custom Query → Execute Query (Returns one matching row)

FAQ

How does authentication work for PostgreSQL in Konnectify?

Konnectify connects using database credentials: host, port, database name, username, and password. Make sure the user has the required permissions for the tables/queries/functions used by your workflow (recommended: least-privilege).

Which PostgreSQL plans or hosting providers are supported?

Any PostgreSQL-compatible database is supported as long as it’s reachable from Konnectify (network access) and allows incoming connections for your user. For managed services (AWS RDS, Cloud SQL, Azure Database, etc.), ensure IP allowlisting/VPC/VPN settings permit connectivity.

How do PostgreSQL triggers work—polling or webhooks?

These triggers are poll-based. Konnectify runs your configured table scan or SELECT query on a schedule and uses a cursor to keep track of what has already been processed, helping avoid reprocessing older rows.

How can I prevent duplicates?

This connector doesn’t include an “upsert” action by default. For duplicate prevention, use cursor-based polling with a stable ordering column (e.g., incrementing ID), and optionally add a lookup step (single-row query) to check for an existing record before proceeding with downstream actions.

How are rate limits and timeouts handled?

PostgreSQL itself doesn’t enforce “API rate limits,” but your hosting provider may enforce connection limits, query timeouts, or CPU/memory thresholds. If a query fails intermittently, reduce polling frequency, optimize queries (indexes, smaller result sets), and confirm provider-side limits and max connections.

Can I connect multiple PostgreSQL databases?

Yes. Create multiple PostgreSQL connections in Konnectify—one per host/database/user as needed—then select the correct connection in each workflow step.

How do {{placeholders}} work in query actions?

In query actions, you can use {{placeholder}} tokens to inject values from previous workflow steps (for example, an ID from a trigger). Make sure your query is a SELECT statement for these actions, and keep the placeholders aligned with the inputs you map in Konnectify.
