PostgreSQL is a widely used open-source relational database management system in enterprise applications. Amazon Redshift, in turn, is a cloud data warehouse designed for fast, efficient analytics on large volumes of data

With Erathos, you can integrate PostgreSQL data into Redshift in just minutes. Our platform handles the entire data movement process into your analytics environment and makes it easy to join that data with other sources in your Data Warehouse. That way, your time is spent on what really drives value — extracting actionable insights and making more data-driven decisions.

### What PostgreSQL data does Erathos sync to Redshift?

The integration automatically syncs the main PostgreSQL objects:

- **Selected tables** — incremental replication of any configured table
- **Schema drift** — newly detected columns are automatically added to the destination
- **Primary keys and timestamps** — used for efficient incremental syncing
- **Historical data** — a full initial load followed by incremental updates

### Why sync PostgreSQL with Redshift?

Keeping an analytical copy of PostgreSQL operational data in Redshift ensures heavy queries don't impact production app performance. With incremental replication and schema drift detection, your data warehouse stays up to date while the transactional database remains stable and responsive.

### How it works

Erathos connects to PostgreSQL via the official API and syncs your data incrementally — only new or updated records are processed on each run, keeping pipelines fast and Redshift costs predictable. You choose the sync frequency (from every 5 minutes to daily), which objects to sync, and the target dataset. Every run is fully observable: execution time, rows processed, errors with context, and instant alerts via Slack or email if anything goes wrong.

## Data in your data warehouse in minutes

### Ready-to-use PostgreSQL connector

Replicate PostgreSQL tables to Redshift with incremental sync and automatic schema drift detection—without breaking pipelines when the schema changes.

### Full control over your PostgreSQL pipelines

Set sync frequency and type per table. Incremental synchronization for Redshift — only new records processed in each run, without reprocessing everything from scratch.

### End-to-end observability

Stop discovering PostgreSQL issues only after the business team starts complaining. Every run is logged with execution time, processed rows, and error context. Get automatic alerts via Slack, Discord, or email the moment something goes off track — keeping replication up to date without putting your transactional database at risk.

## Centralizing PostgreSQL data in Redshift has never been easier

Erathos is a data ingestion platform for teams that need to replicate operational databases for analytics. With the PostgreSQL connector, you can incrementally sync transactional tables and records to Redshift—with schema drift detection and complete logs for every run.

## FAQ

### What is Erathos and how can it help my company?

Erathos is a data ingestion platform built for reliability, transparency, and control. We help data teams connect tools like PostgreSQL to their data warehouse—with full observability into every run, zero maintenance, and none of the opacity of traditional market tools.

### How does Erathos synchronize data from PostgreSQL to Redshift?

Erathos uses incremental replication to sync PostgreSQL tables to Redshift. Schema drift is automatically detected—if a column is added or changed in PostgreSQL, the pipeline adapts without manual intervention.

### How often does Erathos synchronize data from PostgreSQL to Redshift?

You can configure sync frequency at the table level from every 5 minutes up to once daily. Erathos uses incremental synchronization—only new or updated records are processed on each run—keeping your PostgreSQL pipeline efficient and Redshift costs predictable.

### What happens if a PostgreSQL sync fails?

Erathos automatically detects failures and sends alerts to your email, Slack, or Discord with full context—not just "job failed." Smart retries handle transient errors, and every execution is logged with run time, processed rows, and error context so your team can debug in minutes, not hours.

### Is there a free trial period for the PostgreSQL connector?

Yes. Every Erathos connector includes a 14-day free trial. Connect PostgreSQL to Redshift and start syncing immediately—no credit card required.
