pgoutput-client provides a PostgreSQL logical replication transport for Ruby. It manages replication connections, lifecycle, monitoring, keepalive handling, graceful shutdown, and transport-level acknowledgment boundaries while streaming pgoutput messages to downstream consumers. pgoutput-client owns transport. Parsers, decoders, source adapters, runtimes, and sinks remain separate concerns within the CDC ecosystem.
