Install and run a PostgreSQL database locally on Linux, MacOS or Windows. PostgreSQL can be bundled with your application, or downloaded on demand.

This library provides an embedded-like experience for PostgreSQL similar to what you would have with SQLite. This is accomplished by downloading and installing PostgreSQL during runtime. There is also a "bundled" feature that when enabled, will download the PostgreSQL installation archive at compile time, include it in your binary and install from the binary version at runtime. In either case, PostgreSQL will run in a separate process space.

• installing and running PostgreSQL
• running PostgreSQL on ephemeral ports
• async and blocking API
• bundling the PostgreSQL archive in an executable
• dynamic version resolution
• ability to configure PostgreSQL startup options
• URL based configuration
• choice of native-tls vs rustls

use postgresql_embedded::{PostgreSQL, Result};

#[tokio::main]
async fn main() -> Result<()> {
    let mut postgresql = PostgreSQL::default();
    postgresql.setup().await?;
    postgresql.start().await?;

    let database_name = "test";
    postgresql.create_database(database_name).await?;
    postgresql.database_exists(database_name).await?;
    postgresql.drop_database(database_name).await?;

    postgresql.stop().await
}
