+- A [`PostgresConnection`] which allows you to connect to, authorize with, query, and retrieve results from a PostgreSQL server
 - An async/await interface that supports backpressure 
 - Automatic conversions between Swift primitive types and the Postgres wire format
 - Integrated with the Swift server ecosystem, including use of [SwiftLog].

-While this looks at first glance like a classic case of [SQL injection](https://en.wikipedia.org/wiki/SQL_injection) 😱, PostgresNIO's API ensures that this usage is safe. The first parameter of the `query(_:logger:)` method is not a plain `String`, but a `PostgresQuery`, which implements Swift's `ExpressibleByStringInterpolation` protocol. PostgresNIO uses the literal parts of the provided string as the SQL query and replaces each interpolated value with a parameter binding. Only values which implement the `PostgresEncodable` protocol may be interpolated in this way. As with `PostgresDecodable`, PostgresNIO provides default implementations for most common types.

-Some queries do not receive any rows from the server (most often `INSERT`, `UPDATE`, and `DELETE` queries with no `RETURNING` clause, not to mention most DDL queries). To support this, the `query(_:logger:)` method is marked `@discardableResult`, so that the compiler does not issue a warning if the return value is not used.
