SQL Server + PostgreSQL
SQL Server is a relational database management system developed by Microsoft, used to store and manage large volumes of data. PostgreSQL, on the other hand, is an open-source relational database management system that is highly robust and scalable. It supports a broad range of data types and advanced features.
With Erathos, you can integrate data from SQL Server into PostgreSQL in just a few minutes. Our platform handles the entire data movement process into your analytics environment and makes it easy to blend that data with other sources in your data warehouse. That way, your time goes where it actually creates value—extracting actionable insights and making more data-driven decisions.
What SQL Server data does Erathos sync to PostgreSQL?
The integration automatically syncs the main SQL Server objects:
Selected tables — incremental replication of any configured table
Schema drift — new columns detected and added automatically to the destination
Primary keys and timestamps — used for efficient incremental sync
Historical data — full initial load followed by incremental updates
Why sync SQL Server with PostgreSQL?
Keeping an analytical copy of SQL Server operational data in PostgreSQL ensures heavy queries don't impact 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 SQL Server through 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 every 5 minutes to daily), the objects to sync, and the target dataset. Each run is fully observable: execution time, rows processed, errors with context, and instant alerts via Slack or email if anything goes wrong.
No credit card required.
Why do data teams choose Erathos for SQL Server?
Ready-to-use SQL Server connector
Replicate SQL Server tables to PostgreSQL with incremental synchronization and automatic schema drift detection—without breaking pipelines when the structure changes.
Total control over your SQL Server 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 finding out SQL Server failed only after the business team complains. Every run is logged with runtime, processed row counts, and error context. Automatic alerts via Slack, Discord, or email as soon as anything deviates from expected behavior — keeping replication up to date without impacting the transactional database.
Why companies are moving data from SQL Server to PostgreSQL with Erathos
Centralizing SQL Server 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 SQL Server connector, you can sync tables and transactional 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 SQL Server to their data warehouse—with full observability into every run, zero maintenance, and none of the black-box opacity of traditional market tools.
How does Erathos synchronize data from SQL Server to PostgreSQL?
Erathos uses incremental replication to synchronize tables from SQL Server to PostgreSQL. Schema drift is automatically detected—if a column is added or modified in SQL Server, the pipeline adapts without manual intervention.
How often does Erathos synchronize data from SQL Server to PostgreSQL?
You can configure sync frequency at the table level, from every 5 minutes up to once a day. Erathos uses incremental sync—only new or updated records are processed on each run, keeping the SQL Server pipeline efficient and PostgreSQL costs predictable.
What happens if a SQL Server synchronization 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 SQL Server connector?
Yes. Every Erathos connector includes a 14-day free trial. Connect SQL Server to PostgreSQL and start syncing immediately—no credit card required.
