Copy Data from SQL Server to PostgreSQL Automatically
Need to copy data from Microsoft SQL Server to PostgreSQL? Advanced ETL Processor lets you automate the entire process - no SQL scripting, no programming, and no external tools required.
Why Copy SQL Server Data to PostgreSQL?
- Modernize legacy infrastructure with open-source technologies
- Migrate from commercial RDBMS to a cost-effective PostgreSQL platform
- Enable cross-database reporting, integration, and analytics
SQL Server and PostgreSQL - Powerful, Flexible, Compatible
SQL Server is a mature, enterprise-grade relational database. PostgreSQL is a robust open-source alternative known for extensibility, standards compliance, and performance. With Advanced ETL Processor, transferring data between them is fast, repeatable, and code-free.
How to Copy Data from SQL Server to PostgreSQL - Step-by-Step
1. Launch Advanced ETL Processor
- Create a SQL Server Connection using server name, database name, authentication type, and credentials
- Create a PostgreSQL Connection with host, port, database name, username, and password
2. Create a New Transformation
Right-click on a transformation group and choose New to define a new workflow.
3. Configure Reader
- Double-click the reader component to open Reader Properties
- Select your SQL Server connection
- Choose a table or write a custom SQL SELECT query
4. Configure Writer
- Double-click the writer component to open Writer Properties
- Select the PostgreSQL connection
- Specify the target table and insert mode (append, truncate, replace)
5. Map and Format Fields
- Map SQL Server fields to PostgreSQL columns
- Apply necessary transformations or data type conversions
6. Run the Transformation
Click the Run button (Green Arrow). The data will be copied from SQL Server to PostgreSQL with logging, rollback, and error-handling features active.
Automate and Monitor
- Schedule the transfer process to run at specific intervals
- Trigger based on database events, file changes, or custom logic
- Enable detailed logging, error recovery, and audit trails
Where this copy workflow fits
Copy Data from SQL Server to PostgreSQL is useful when you need database migration, scheduled database copy jobs, repeatable row transfers, or an ETL data transfer workflow between operational systems and reporting stores. It can also work as a database replication alternative when you need mapping, validation, transformations, and logs more than low-level continuous replication.
Typical use cases include moving SQL Server records into PostgreSQL for reporting, syncing a legacy application with a newer database, feeding a warehouse, or replacing manual exports with a controlled schedule.

Business usage examples
Operations lead
Move database rows through repeatable copy workflows instead of manual exports and imports.
Data team
Map fields between Access, SQL Server, MySQL, PostgreSQL, Oracle, Salesforce, and other systems.
Compliance owner
Keep source queries, target writes, run logs, and failures visible enough for audit work.

FAQ
Can Advanced ETL Processor copy data from SQL Server to PostgreSQL?
Yes. Advanced ETL Processor can read SQL Server, write to PostgreSQL, map fields, validate rows, and log the transfer.
What should I check before copying SQL Server data to PostgreSQL?
Check source queries, target tables, key fields, data types, date handling, null values, and write mode before scheduling the SQL Server to PostgreSQL workflow.
Is this a SQL Server to PostgreSQL replication tool?
It is better described as a scheduled database copy and ETL data transfer workflow. Use it when you need controlled moves, transformations, validation, and run logs rather than low-level database replication.
Do I need to write SQL scripts?
No scripting is required for the normal copy workflow. You can still use SQL where it helps, but the routine work is configured visually.
When should I not automate the copy yet?
Do not automate it until the source tables, target tables, key fields, and failure rules are clear. Automation repeats rules; it does not rescue vague ones.
Can I test the transfer before buying?
Yes. Download the fully functional 30-day trial, build one small transfer, and test it with a safe sample first.
