Can you integrate PostgreSQL with Scaleway Postgres?

Explore a PostgreSQL and Scaleway Postgres integration with a Stacksync engineer. Stacksync support for Scaleway Postgres is not established by the connector documentation reviewed for this page. Start with one record and the update your business needs to identify an implementation path.

Can PostgreSQL and Scaleway Postgres sync in both directions?

Confirm two-way support with Stacksync for the records and fields you need in both systems. Access to a vendor API does not confirm that its Stacksync connector supports write-back.

What should be ready before the PostgreSQL and Scaleway Postgres initial load?

Prepare both accounts, the selected object schemas, stable source and destination IDs, and the expected outcome. Use a single-column primary key with a database-generated default for every selected table; composite primary keys are not supported. Identify the Scaleway Postgres account, edition, environment, and business objects the integration must access. Use the pair worksheet to record ownership and acceptance criteria.

How fast does the PostgreSQL to Scaleway Postgres sync run?

Measure initial-load and ongoing-change latency separately. Source detection, selected objects, account limits, and destination validation determine the observed delay.

Will existing duplicates merge automatically?

No. Stacksync documents that pre-existing duplicates are not merged automatically when two-way sync begins. Review the initial dataset and matching plan before enabling it; an empty destination can simplify the first load.

How do I map PostgreSQL fields to Scaleway Postgres?

Start with one business entity and a stable record ID. Map a small set of editable fields with compatible types, test required values and relationships, then expand after the pilot passes.

What should I do if a record fails to sync?

Check the destination error, field constraints, permissions, and current source value. The Stacksync issues dashboard supports retry and revert; retry reads current source values, so verify the intended record state before acting.

What does a PostgreSQL and Scaleway Postgres integration cost?

Use the current Stacksync pricing page and confirm the supported implementation with the team. Scope the required objects, record volume, update frequency, initial load, and support needs when comparing a managed connector with native or custom development.

Proposed workflow

Plan table mappings between PostgreSQL and Scaleway Postgres

This is an evaluation scenario; connector and operation support require confirmation.

Starting eventA selected source table needs an operational replica, a reporting projection, or a migration copy.

Choose actual tables in PostgreSQL and Scaleway Postgres and compare their schemas and record types.
Specify the primary/business key, type conversions, filter boundaries, relationship dependencies, and the source of each writable field.
Plan two-way sync around connector support and your update rules; use a source-to-destination copy for read-only records. Keep source views, aggregate outputs, and writable base tables distinct.

What to verifyCounts reconcile within identical filters; updates preserve keys; precision, nulls, deletes, and schema changes follow the agreed mapping rules.

Authentication, permissions and API limits

Connection requirements and limits

PostgreSQL

Integration interface: 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: The Postgres connector uses logical replication. The separate Postgres Heroku connector uses database triggers when replication rights are unavailable.
Read access: Available for supported records
Write access: Available for supported records

Setup requirements

Use a single-column primary key with a database-generated default for every selected table; composite primary keys are not supported.
Give the connected database role the required ownership and replication rights. Logical replication requires wal_level=logical; check the hosted database procedure before changing it.
For PostgreSQL 12 and earlier, have the database administrator install the pgcrypto extension before starting the sync so tracking tables can use gen_random_uuid(). PostgreSQL 13 and later provide this function without the extension.

Limitations to check

Renaming a schema, table, or column requires updating the sync configuration.
Database views cannot be used as writable destinations in two-way sync; validate the selected connector and view support separately.

Compare integration approaches

Choose a method around one example record and the update your business needs. Define how the PostgreSQL source record should appear or trigger work in Scaleway Postgres. Compare ongoing sync, a custom workflow, and a scheduled export against that requirement.

Stacksync managed sync

Best fit: Review compatibility with a Stacksync engineer using an example of the records and updates you need.
Operating responsibility: Fits ongoing record synchronization when the required operations are supported. Add workflow steps for approvals or business actions that go beyond copying fields.
Before you choose: Provide your table or object schemas and one example update; confirm the supported keys, fields, and direction.

Native vendor integration

Best fit: A vendor-built integration may fit if it supports your PostgreSQL and Scaleway Postgres record types.
Operating responsibility: Can reduce setup for a supported workflow. You may need another method for records or business steps it does not cover.
Before you choose: First check whether either vendor offers this integration. If available, verify your record types, update direction, account tier, and related-record handling.

Custom API or workflow

Best fit: Consider when PostgreSQL and Scaleway Postgres need a transformation, approval, or action outside a direct record sync.
Operating responsibility: Provides control over business steps; the team owns credentials, version changes, error queues, and reconciliation.
Before you choose: Verify endpoint permissions, pagination, quotas, duplicate detection, and failure recovery.

File or scheduled snapshot

Best fit: Consider for a one-time PostgreSQL / Scaleway Postgres migration or a reporting need with an explicit freshness window.
Operating responsibility: Can simplify a bounded transfer; later changes and deletion history require another extraction or a separately designed incremental process.
Before you choose: Record the extraction cutoff, source IDs, encoding, date/number formats, and reconciliation totals.

Workflow scenarios and expected results

Plan table mappings between PostgreSQL and Scaleway Postgres

This is an evaluation scenario; connector and operation support require confirmation.

Starting event: A selected source table needs an operational replica, a reporting projection, or a migration copy.

Choose actual tables in PostgreSQL and Scaleway Postgres and compare their schemas and record types.
Specify the primary/business key, type conversions, filter boundaries, relationship dependencies, and the source of each writable field.
Plan two-way sync around connector support and your update rules; use a source-to-destination copy for read-only records. Keep source views, aggregate outputs, and writable base tables distinct.

Expected result: Counts reconcile within identical filters; updates preserve keys; precision, nulls, deletes, and schema changes follow the agreed mapping rules.

If it fails: Compare current source state, key mapping, and destination constraints before retrying. Reconcile the backlog after any schema or permission change.

Initial load and acceptance testing

Keep both record IDs with the expected and actual result. Reconcile the same filters and time window in each system.

Direction and permissions

Test case

Bring an example source record and the intended destination operation to the compatibility review. Confirm the supported route before granting write access.

Expected result

Only an approved, supported direction and permitted fields are written.

Schema, keys, and reconciliation

Test case

Use an actual PostgreSQL and Scaleway Postgres table. Compare key uniqueness, nulls, decimal precision, timezone conversions, and counts within identical filters.

Expected result

The process meets its agreed freshness target and reconciliation has no unexplained differences.

Failed updates, retries and recovery

Start with the failed record and the destination error, then inspect the source value, field requirements, and access.

A record type or update is unavailable

Investigate

Check the PostgreSQL and Scaleway Postgres connector guides, account permissions, and any operations marked On Request.

Next action

Ask the integration team to confirm a supported way to handle that record. Verify whether it needs connector configuration or a separate workflow step.

Source and destination disagree after a retry

Investigate

Compare current source values, destination validation, identity mappings, and any side effects already completed.

Next action

Stacksync issue retry reads the current source state. Decide the intended state before retrying or reverting; reconcile downstream effects separately.

Read the Stacksync issues dashboard guide for retry and revert behavior.
