Copy Data from Oracle to PostgreSQL Automatically
Looking to migrate or synchronize your Oracle database with PostgreSQL? With Advanced ETL Processor, you can automate the entire process - no manual coding, no SQL scripts, and no complex tools required.
Why Copy Oracle Data to PostgreSQL?
- Enable database modernization and open-source adoption
- Reduce licensing costs and infrastructure overhead
- Support analytics, cloud integration, or hybrid deployments
Why Oracle and PostgreSQL?
Oracle is a widely used enterprise-grade database. PostgreSQL is a powerful, open-source RDBMS favored for flexibility, standards compliance, and advanced features. Copying data between them bridges commercial and open ecosystems.
How to Copy Data from Oracle to PostgreSQL - Step-by-Step
1. Launch Advanced ETL Processor
- Create an Oracle Database Connection with your connection string, port, and credentials
- Create a PostgreSQL Connection by entering host, port, database, username, and password
2. Create a New Transformation
In the transformation tree, right-click on a group and select New to begin building the workflow.
3. Configure Reader
- Double-click the reader object to open Reader Properties
- Select your Oracle connection
- Choose the source table or define a SQL SELECT query
4. Configure Writer
- Double-click the writer object to open Writer Properties
- Select the PostgreSQL connection as the target
- Specify the destination table and insert options (append, truncate, overwrite)
5. Map and Format Fields
- Map Oracle source fields to PostgreSQL columns
- Convert data types or apply transformations if needed
6. Run the Transformation
Click the Run button (Green Arrow). Data will be transferred from Oracle to PostgreSQL instantly, with high performance and data integrity.
Automate and Monitor
- Schedule jobs to run hourly, daily, or on-demand
- Trigger jobs based on external events or file changes
- Log execution history, send alerts, and enable rollback on failure
Where this copy workflow fits
Copy Data from Oracle 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 Oracle 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 Oracle to PostgreSQL?
Yes. Advanced ETL Processor can read Oracle, write to PostgreSQL, map fields, validate rows, and log the transfer.
What should I check before copying Oracle data to PostgreSQL?
Check source queries, target tables, key fields, data types, date handling, null values, and write mode before scheduling the Oracle to PostgreSQL workflow.
Is this a Oracle 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.
