Why teams connect PostgreSQL and Scaleway Postgres

Keep PostgreSQL and Scaleway Postgres synchronized in real time, across engines, regions, or services, in one or both directions.

Two databases that must agree is one of the oldest problems in engineering: different engines for different workloads, separate services with overlapping reference data, a migration in flight, or regional instances that share a subset of records. Hand-rolled replication across systems means change capture, conflict handling, and type mapping, all built and maintained by your team.

Stacksync syncs tables or collections between PostgreSQL and Scaleway Postgres continuously and bi-directionally, translating types between the two engines and resolving conflicts by rules you configure. Rows written on either side appear on the other within seconds.

Common use cases

  • Let an application write to its own database and have those rows appear as records in business systems in near real time
  • Consolidate data from several microservice databases into one operational Postgres store
  • Keep an EU-hosted Postgres as the system of record while distributing data to US-hosted SaaS applications
  • Sync production tables from Scaleway Postgres into a CRM so sales and support see live product usage on customer records

Shared reference data between services

Services that own separate databases stay consistent on the records they share, without a custom replication layer.

Regional or environment copies

Mirror selected tables to another region or environment continuously, filtered to just the rows that should travel.

Cross-engine sync

Keep the same dataset live in both PostgreSQL and Scaleway Postgres, so each workload runs on the engine that suits it.

What you can sync between PostgreSQL and Scaleway Postgres

Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.

PostgreSQL objects Scaleway Postgres objects
Materialized Views Precomputed result sets synced outward on a refresh schedule. Columns Postgres-native types, including JSONB and arrays, are mapped to fields in the paired system.
Schemas Namespaces that scope which tables a sync reads and writes. Tables Primary sync unit; each table maps to an object or table on the other side of the sync.
Columns Field-level mapping targets; types are mapped to the connected system's field types. Views Read-only sources for shaping data before it leaves the database.
Primary and Unique Keys Used as match keys for idempotent upserts and conflict resolution. Materialized views Precomputed result sets that can be read on a schedule for downstream syncs.
JSONB Columns Hold semi-structured payloads such as nested SaaS objects or metadata. Schemas Namespace tables so multiple applications or environments can be synced selectively.
Sequences Generate surrogate keys for rows created by inbound syncs. Sequences Generate primary keys; sync tooling must respect them when writing rows.

How the PostgreSQL and Scaleway Postgres connectors work

PostgreSQL

Integration surface
SQL wire protocol (PostgreSQL frontend/backend protocol)
Authentication
Database credentials (connection string or parameters), with optional SSL root certificate upload and optional SSH tunnel (SSH user + host); a least-privilege DB user
Change detection
Logical replication (wal_level = logical) for change data capture via the "Postgres" connector; database triggers (TRIGGER grant + stacksync_logging schema) via the trigger-based "Postgres Heroku" connector where
Capabilities

Rate limits
No API rate limits; throughput is bounded by connection limits, instance resources, and replication slot throughput
