Can you integrate PostgreSQL with Supabase?

Yes. Stacksync provides a managed, real-time two-way integration between PostgreSQL and Supabase: authenticate both systems, choose the objects to sync (such as PostgreSQL's Sequences and Custom Types and Enums), map fields visually, and changes propagate both ways in milliseconds — no code required.

Can the PostgreSQL–Supabase sync run one-way instead of two-way?

Yes. Each object mapping can be bidirectional or restricted to a single direction (both systems accept writes). Read-only mirrors, one-way pushes, and full two-way sync can be mixed in the same integration.

How do teams use the PostgreSQL and Supabase integration?

Common patterns for PostgreSQL and Supabase: Regional or environment copies; Cross-engine sync; Migration with zero-downtime cutover. Mirror selected tables to another region or environment continuously, filtered to just the rows that should travel.

What should I know about the two APIs?

PostgreSQL: 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. Supabase: Direct PostgreSQL wire protocol connection, plus an auto-generated REST API (PostgREST). Authentication: Database credentials (connection string) for SQL access; API keys (anon / service role) for the REST layer. Stacksync manages authentication, retries, and rate limits on both sides.

What makes PostgreSQL's data model different?

PostgreSQL: INSERT ... ON CONFLICT gives native upsert semantics, which makes inbound syncs idempotent against primary or unique keys. Supabase: Every Supabase project is a full PostgreSQL database, so standard Postgres drivers, SQL tooling, and log-based CDC apply directly. Stacksync's field mapping accounts for these differences between PostgreSQL and Supabase without custom code.

Is the PostgreSQL–Supabase integration secure?

Stacksync is SOC 2 Type II and ISO 27001 certified with HIPAA BAA support. Data is encrypted in transit, and a zero-persistent-storage architecture means PostgreSQL and Supabase records are not retained after a sync operation.

Why teams connect PostgreSQL and Supabase

Keep PostgreSQL and Supabase 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 Supabase 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
Reflect auth.users state into support and CRM systems so teams see account status without querying the database
Push product events captured in Supabase Postgres to marketing tools for lifecycle campaigns

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 Supabase, 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 PostgreSQL and Supabase

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		Supabase objects
Sequences Generate surrogate keys for rows created by inbound syncs.	⇄	Storage Object Metadata File metadata rows that can be joined to synced application data.
Custom Types and Enums Constrain synced values to a fixed set, mirroring picklist fields.	⇄	Tables Standard Postgres tables; the primary two-way sync target.
Tables The primary sync target; rows map one-to-one to records in connected SaaS systems.	⇄	Views Read-side projections exposed to outbound syncs.
Views Read-side projections used to expose joined or filtered data to a sync.	⇄	Schemas Namespaces (public and custom) that scope sync access.
Materialized Views Precomputed result sets synced outward on a refresh schedule.	⇄	auth.users Managed authentication users, often mirrored into CRM or support systems.
Schemas Namespaces that scope which tables a sync reads and writes.	⇄	Row Level Security Policies Row-level access rules that govern what the REST layer exposes.

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

Supabase
