Why teams connect PostgreSQL and YugabyteDB

Keep PostgreSQL and YugabyteDB 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 YugabyteDB 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

  • Feed reporting and BI from a continuously synced Postgres replica instead of scheduled ETL scripts
  • Expose SaaS objects (CRM contacts, ERP invoices, support tickets) as Postgres tables that internal tools can query and join
  • Sync reference data such as pricing or entitlements from an ERP into YugabyteDB for globally distributed low-latency reads.
  • Consolidate data from regional YugabyteDB clusters into one reporting store.

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.

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.

What you can sync between PostgreSQL and YugabyteDB

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 YugabyteDB objects
Sequences Generate surrogate keys for rows created by inbound syncs. Databases and Keyspaces Top-level containers for the YSQL (Postgres-style) and YCQL (Cassandra-style) APIs respectively.
Custom Types and Enums Constrain synced values to a fixed set, mirroring picklist fields. Tables Distributed SQL tables split into tablets; the primary read and write targets.
Tables The primary sync target; rows map one-to-one to records in connected SaaS systems. Indexes Global secondary indexes maintained transactionally alongside table writes.
Views Read-side projections used to expose joined or filtered data to a sync. Materialized Views Precomputed query results available in YSQL for read-side shaping.
Materialized Views Precomputed result sets synced outward on a refresh schedule. Schemas Postgres-style namespaces in YSQL used to organize synced data.
Schemas Namespaces that scope which tables a sync reads and writes. Sequences ID generation objects relevant when syncing writes into YSQL tables.
