Our verdict on pgstream

pgstream is an open-source, self-hosted PostgreSQL change data capture command-line tool and Go library. It is designed for teams that need to replicate PostgreSQL data and schema changes into PostgreSQL, Elasticsearch, OpenSearch, Kafka, webhooks, or custom destinations. That makes it a focused fit for PostgreSQL replication, search indexing, event streaming, environment synchronization, and workflows that need control over their deployment.

Its standout capability is the combination of logical WAL replication with DDL and schema-change tracking. pgstream can take initial and on-demand PostgreSQL snapshots, then continue replicating data changes while carrying schema changes with them. Column-value transformations support data anonymization, which is useful when replicated data needs to be adjusted for another environment. Kafka schema-based partitioning adds a purpose-built option for event-streaming workflows, while OpenTelemetry metrics and distributed tracing provide observability signals for the replication process.

The target ecosystem covers PostgreSQL, Elasticsearch, OpenSearch, Kafka, and webhooks, with a Go library for building custom targets. Integrations with Greenmask, Neosync, and go-masker extend the surrounding data-management options. The trade-off is a narrow source focus: pgstream centers on PostgreSQL rather than serving as a multi-database CDC layer. Teams standardizing on PostgreSQL and needing custom destinations should consider it; teams requiring capture from multiple database systems should choose a broader alternative.
