Synthetic Data Generation with PostgreSQL
Synthetic Data Generation built on PostgreSQL, chosen where it genuinely fits, and swapped where it does not.

Why PostgreSQL for this
We validate transfer. A model that performs on synthetic data and fails on real data has learned the generator rather than the phenomenon, and that check is the deliverable.
PostgreSQL is strongest at it handles far more workload than teams expect, with one operational model. For synthetic data generation that matters because the failure modes of this kind of system tend to cluster exactly there.
The honest trade-off: genuine analytical workloads past a certain scale belong in a warehouse. We say that up front because a stack chosen for fashion rather than fit becomes someone's migration project two years later. We start from the constraint, not the capability, what the system must never do, who signs off, and what happens when it is wrong.
You own the code, the models where they are open-weight, and the documentation to run it without us.

We are not a reseller for PostgreSQL and hold no commission on this choice. Where a different option fits your workload better, the recommendation will say so. That is the entire value of asking us.
What is included
- Statistical profiling of the source so the synthetic set preserves real relationships
- Privacy evaluation, including re-identification risk testing
- Class balancing and rare-event augmentation where models need it
- Realistic test datasets for non-production environments
- Validation that models trained on synthetic data actually transfer
- Documentation for your DPO and auditors
Questions
Is synthetic data private by default?
No. Privacy depends on how it was generated and must be tested. We run re-identification risk assessment rather than asserting anonymity, because regulators ask for evidence.
Can we train production models on it?
Sometimes, particularly for augmentation and class balancing. We validate performance on held-out real data before recommending it for production training.
Does it satisfy DPDP requirements?
Properly generated and tested synthetic data can reduce personal-data exposure meaningfully. We document the method and the risk assessment so your DPO can make that determination.
Alternatives for synthetic data generation
Same capability, different stack. Each page states its own trade-off.
