Why teams connect Amazon Lightsail and PostgreSQL

Keep Amazon Lightsail and PostgreSQL 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 Amazon Lightsail and PostgreSQL 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

  • Sync a Lightsail-hosted application database with a CRM so customer records match what the app stores.
  • Push cleaned or enriched records from central systems back into the Lightsail database behind a small web app.
  • Consolidate data from several microservice databases into one operational Postgres store
  • Feed reporting and BI from a continuously synced Postgres replica instead of scheduled ETL scripts

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 Amazon Lightsail and PostgreSQL, so each workload runs on the engine that suits it.

Migration with zero-downtime cutover

When one database is replacing the other, sync both directions during the transition and switch traffic when ready, without a freeze window.

What you can sync between Amazon Lightsail and PostgreSQL

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.

Amazon Lightsail objects PostgreSQL objects
Users and Grants Database accounts used to give the sync connection scoped access. Materialized Views Precomputed result sets synced outward on a refresh schedule.
Managed Databases Lightsail-hosted MySQL or PostgreSQL instances that a sync connects to as standard databases. Schemas Namespaces that scope which tables a sync reads and writes.
Databases Logical databases on the instance that scope a connection. Columns Field-level mapping targets; types are mapped to the connected system's field types.
Schemas Namespaces used when selecting tables to sync. Primary and Unique Keys Used as match keys for idempotent upserts and conflict resolution.
Tables Relational tables read from and written to at row level. JSONB Columns Hold semi-structured payloads such as nested SaaS objects or metadata.
Views Query-backed read-only sources. Sequences Generate surrogate keys for rows created by inbound syncs.

How the Amazon Lightsail and PostgreSQL connectors work

Amazon Lightsail

Integration surface
MySQL or PostgreSQL wire protocol (SQL) to the managed database endpoint
Authentication
Database credentials; public endpoint access must be enabled or a tunnel used
Change detection
Polling on timestamp or key columns; log-based CDC depends on engine parameter access, which is more limited than on full RDS
Capabilities
read · write
Rate limits
No API-style rate limits; capacity is fixed by the chosen Lightsail bundle

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