## What it is
pgsync is a Ruby command-line tool that syncs data from one Postgres database to another, similar to pg_dump/pg_restore. It transfers tables in parallel, supports partial and grouped table syncs, and includes safeguards to keep sensitive data from leaving the server.

## Use cases
- sync data from one postgres database to another
- copy production data to a local development database
- sync specific tables or rows between postgres databases
- refresh staging database with production data safely
- sync a record and its related records across databases
- handle schema differences when syncing postgres data

## When to choose
- you need fast, parallel data transfer between two Postgres databases
- you want to sync partial tables, filtered rows, or related record groups
- you need to avoid copying sensitive data off a server
- your databases may have slightly different schemas

## When to avoid
- you need to sync between different database engines, not just Postgres
- you need continuous or real-time replication rather than one-off syncs
- you need to sync schema changes as the primary goal - use a migration tool
