Comments (1)

alzhi · 1d ago

pgrwl is a PostgreSQL write-ahead log (WAL) receiver written in Go.

It’s a drop-in, container-friendly alternative to pg_receivewal, supporting streaming replication, encryption, compression, and remote storage (S3, SFTP).

Designed for disaster recovery and PITR (Point-in-Time Recovery), pgrwl ensures zero data loss (RPO=0) and seamless integration with Kubernetes environments.
