# Migrate MySQL, SQLite, or CSV data into PostgreSQL with repeatable load files before cutover with pgloader

Move data into PostgreSQL with declarative load files, built-in type conversion, and repeatable migration runs before one-off import scripts become cutover risk.

## Prerequisites

pgloader and access to source systems plus a PostgreSQL target

## Installation

Use the upstream install or setup path that matches your environment:
- $ docker pull ghcr.io/dimitri/pgloader:latest
- $ docker run --rm -it ghcr.io/dimitri/pgloader:latest pgloader --version

Requirements and caveats from upstream:
- If you're using docker, you can use the latest version built by the CI at

Basic usage or getting-started notes:
- pgloader also implements data reformatting, a typical example of that
- --help -h boolean Show usage and exit.
- --dry-run boolean Only check database connections, don't load anything.
