## Description

pg_easy_replicate is a command-line utility designed to orchestrate database migrations and logical replication between PostgreSQL instances. It functions as a migration orchestrator that manages the entire lifecycle of data synchronization, from initial schema propagation to the final transition of application traffic.

The tool distinguishes itself through state-aware switchover logic, which coordinates the movement of operations by verifying replication lag and enforcing write locks to prevent data loss. It provides granular control over data movement by allowing users to organize tables into specific replication groups, ensuring that only intended records are synchronized between the source and target environments.

Beyond core migration tasks, the project includes comprehensive monitoring capabilities to track synchronization health and replication lag in real time. It supports integration with external systems by pushing status updates and replication metrics to configured webhook endpoints, facilitating automated observability within existing infrastructure workflows.
