pgcopy

pgcopy is a Go-based solution designed to replicate data from one PostgreSQL database to another. It supports data migration across multiple tables, ensuring that data types are handled correctly during the copy process.

Features

• Connects to both source and target PostgreSQL databases.
• Replicates data from specified tables in the source database to the target database.
• Handles various data types including integers, floats, strings, and booleans.
• Ensures type safety during data replication.
• Supports configuration via a YAML file.

Requirements

• Go 1.21.2 or later
• PostgreSQL 12 or later
