A configurable library for downloading and extracting PostgreSQL archives.

## Examples

### Asynchronous API

```rust
use postgresql_archive::{extract, get_archive, Result, VersionReq};
use postgresql_archive::configuration::theseus;

#[tokio::main]
async fn main() -> Result<()> {
    let url = theseus::URL;
    let (archive_version, archive) = get_archive(url, &VersionReq::STAR).await?;
    let out_dir = std::env::temp_dir();
    extract(url, &archive, &out_dir).await
}
```

### Synchronous API

```rust
use postgresql_archive::configuration::theseus;
use postgresql_archive::{Result, VersionReq};
use postgresql_archive::blocking::{extract, get_archive};

fn main() -> Result<()> {
    let url = theseus::URL;
    let (archive_version, archive) = get_archive(url, &VersionReq::STAR)?;
    let out_dir = std::env::temp_dir();
    extract(url, &archive, &out_dir)
}
```
