PostgreSQL is an open-source relational database management system widely used in enterprise applications. Postgres, in turn, is an open-source relational database management system that is highly robust and scalable. It supports a wide range of data types and advanced features.

With Erathos, you can integrate data from PostgreSQL to Postgres in just a few minutes. Our platform handles the entire data movement process into your analytics environment and makes it possible to combine that data with other sources in your data warehouse. That way, your time goes where it actually creates value — uncovering insights and making more data-driven decisions.

### Which PostgreSQL data does Erathos sync to PostgreSQL?

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 synchronization
- **Historical data** — full initial load followed by incremental updates

### Why sync PostgreSQL with PostgreSQL?

Keeping an analytical copy of PostgreSQL operational data in PostgreSQL lets heavy queries run without impacting production application 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 PostgreSQL costs predictable. You choose the sync frequency (from 5 minutes to daily), the objects to sync, and the target dataset. Each run is logged with full observability: runtime, rows processed, errors with context, and instant alerts via Slack or email if something goes wrong.

## Data in your data warehouse in minutes

### Ready-to-use PostgreSQL connector

Replicate tables from PostgreSQL to PostgreSQL with incremental synchronization and automatic schema drift detection—without breaking pipelines when the structure changes.

### Full control over your PostgreSQL pipelines

Configure sync frequency and type by table. Erathos uses intelligent UPSERT in PostgreSQL—ensuring data consistency even during reprocessing.

### 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 PostgreSQL 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 sync transactional tables and records to PostgreSQL incrementally — 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 PostgreSQL?

Erathos uses incremental replication to sync PostgreSQL tables to PostgreSQL. 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 PostgreSQL?

You can configure synchronization frequency from every 5 minutes up to daily, at the table level. Erathos uses incremental synchronization—only new or updated records are processed in each run, keeping the PostgreSQL pipeline efficient and PostgreSQL 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 PostgreSQL and start syncing immediately—no credit card required.
