Export PostgreSQL to QVX Automatically
Looking to export PostgreSQL data into the QVX format for reliable integration with QlikView or Qlik Sense? With Advanced ETL Processor, you can automate the entire process - no scripting, no manual conversions, and no need for Qlik software installed.
What Is a QVX File?
QVX (QlikView Data eXchange) is a Qlik proprietary file format used for transferring data between external systems and Qlik applications. Unlike QVD files, QVX is based on an open XML header and binary body, which makes it well-suited for programmatic exports and integrations.
Why Export PostgreSQL to QVX?
- Integrate PostgreSQL data with QlikView or Qlik Sense
- Optimize dashboard performance by preloading data
- Enable repeatable, automated ETL pipelines into Qlik
Why Use PostgreSQL?
PostgreSQL is a powerful open-source relational database that supports advanced data types, full-text search, JSON, and spatial data. It is widely adopted in analytics, web apps, and data warehousing, making it an ideal backend for Qlik BI platforms.
How to Export PostgreSQL to QVX - Step-by-Step
1. Launch Advanced ETL Processor
- Create a PostgreSQL Connection with host, port, database, and credentials
- Create a Directory Connection for saving the exported QVX file
2. Create a New Transformation
Open or create a transformation group, then click New to build a new transformation.
3. Configure Reader
- Double-click to open Reader Properties
- Select PostgreSQL as the source connection
- Choose a table or write a SQL SELECT statement
4. Configure Writer
- Double-click to open Writer Properties
- Set output format to QVX
- Specify filename and target directory
- Set target table name (optional, used in Qlik)
5. Map and Format Fields
- Map PostgreSQL fields to QVX columns
- Adjust data types, rename fields, or apply formatting
6. Run the Transformation
Click the Run button (Green Arrow) to generate the QVX file. You can now load this file directly into QlikView or Qlik Sense.
Automate and Schedule
- Schedule exports to run daily, hourly, or weekly
- Trigger exports based on events or file changes
- Use logging, error handling, and notifications
Where this export fits
Export PostgreSQL to QVX is useful when PostgreSQL data has to feed reports, dashboards, partner systems, audits, archives, or downstream ETL jobs. Use it when the same source query needs controlled QVX output, validation, scheduling, and logs instead of another manual file export.
Do not automate the export until the source query, output layout, file naming, overwrite rules, and failure behaviour are agreed. Automation repeats rules; it does not rescue unclear ones.

FAQ
Can Advanced ETL Processor export PostgreSQL to QVX?
Yes. Advanced ETL Processor can read PostgreSQL, apply transformations, write QVX, schedule the export, and log the result.
Do I need to write scripts for the export?
No scripting is required for the normal export workflow. You can configure the source, output format, validation, and schedule visually.
Can the QVX export run on a schedule?
Yes. The export package can run on a schedule, write the QVX output, archive files, and keep the same validation rules each time.
Can row counts and failures be logged?
Yes. Add logging so row counts, rejected records, run status, and error details can be reviewed after each export.
What should I check before the first production export?
Check the source query, output columns, data types, date formats, file naming, overwrite rules, archive folder, and failure handling.
Can I export only selected PostgreSQL records?
Yes. Use a query or filter so the export reads only the PostgreSQL records needed for the file, report, dashboard, archive, or partner feed.
When should I not automate the export yet?
Do not automate it until the source query, output layout, file naming, and failure handling are clear. Automation repeats rules; it does not invent them.
Can I test the export before buying?
Yes. Download the fully functional 30-day trial, build one small export, and test it with a safe sample first.
