Postgres ProGate is designed for data migration and replication between different
source and destination databases, later referred to as
sources and destinations.
Postgres ProGate consists of the following components:
procopy — a utility for initial data loading
from a source to a destination.
prosync — a utility for CDC-based replaying
changes to a source on a destination (CDC — change data capture).
procheck — a utility to verify data after
a migration from a source to a destination.
