⚠️ ALPHA QUALITY ⚠️

This project is in the early stages of development. It is far from feature complete. It likely contains many bugs and inconsistencies. Documentation is limited or non-existent. It will change in ways that break backwards compatibility. It is not ready for production use.

That said, if you want to try it out, please do! But bear in mind that it is being updated frequently, at least at the time I'm writing this, and you should expect to update it frequently too. Please check out known issues and file new ones here.

Thanks! Gavin.


pgdo-cli

pgdo CI

A Rust command-line tool for creating standalone PostgreSQL clusters and databases with a focus on convenience and rapid prototyping – such as one sees using SQLite. Scaling down the developer experience to meet individuals working to build something new, build something rapidly, is a key goal of this project.

This is the front-end to pgdo-lib; in that package there's more information about the project as a whole.

Getting started

After installing Cargo, cargo install pgdo-cli will install a pgdo binary in ~/.cargo/bin, which the Cargo installation process will probably have added to your PATH.

Note that this tool does not (yet) come with any PostgreSQL runtimes. You must install these yourself. The pgdo command has some platform-specific smarts and might be able to find those installed runtimes without further configuration. To check, use the runtimes subcommand. If the runtime you want to use doesn't show up, add its bin directory to PATH.

$ pgdo -h
The convenience of SQLite – but with PostgreSQL

Usage: pgdo [OPTIONS] [COMMAND]

Commands:
  shell     Start a psql shell, creating and starting the cluster as necessary (DEFAULT)
  exec      Execute an arbitrary command, creating and starting the cluster as necessary
  clone     Perform a one-off clone/backup of an existing cluster
  backup    Point-in-time backup for an existing cluster
  restore   Point-in-time restore/recovery from a backup made previously with the `backup` command
  runtimes  List discovered PostgreSQL runtimes
  help      Print this message or the help of the given subcommand(s)

Options:
  -h, --help     Print help (see more with '--help')
  -V, --version  Print version

Options for shell:
  -D, --datadir <PGDATA>              The directory in which the cluster lives [env: PGDATA=] [default: cluster]
  -d, --database <PGDATABASE>         The database to connect to [env: PGDATABASE=] [default: postgres]
      --mode <MODE>                   Run the cluster in a "safer" or "faster" mode [possible values: slower-but-safer, faster-but-less-safe]
      --runtime-default <CONSTRAINT>  Select the default runtime, used when creating new clusters
      --destroy                       Destroy the cluster after use. WARNING: This will DELETE THE DATA DIRECTORY. The default is to NOT destroy the cluster

Contributing

If you feel the urge to hack on this code, here's how to get started:

Running the tests

Right now, the pgdo package doesn't have many/any automated tests. That will surely change, but for now, please test your changes manually with as many PostgreSQL runtimes as you can. See pgdo-lib for platform-specific notes on installing runtimes.

Making a release

See pgdo-lib for notes on how to make a release.
