//! A synchronous client for the PostgreSQL database.
//!
//! # Example
//!
//! ```no_run
//! use postgres::{Client, NoTls};
//!
//! # fn main() -> Result<(), postgres::Error> {
//! let mut client = Client::connect("host=localhost user=postgres", NoTls)?;
//!
//! client.batch_execute("
//!     CREATE TABLE person (
//!         id      SERIAL PRIMARY KEY,
//!         name    TEXT NOT NULL,
//!         data    BYTEA
//!     )
//! ")?;
//!
//! let name = "Ferris";
//! let data = None::<&[u8]>;
//! client.execute(
//!     "INSERT INTO person (name, data) VALUES ($1, $2)",
//!     &[&name, &data],
//! )?;
//!
//! for row in client.query("SELECT id, name, data FROM person", &[])? {
//!     let id: i32 = row.get(0);
//!     let name: &str = row.get(1);
//!     let data: Option<&[u8]> = row.get(2);
//!
//!     println!("found person: {} {} {:?}", id, name, data);
//! }
//! # Ok(())
//! # }
//! ```
//!
//! # Implementation
//!
//! This crate is a lightweight wrapper over tokio-postgres. The `postgres::Client` is simply a wrapper around a
//! `tokio_postgres::Client` along side a tokio `Runtime`. The client simply blocks on the futures provided by the async
//! client.
//!
//! # SSL/TLS support
//!
//! TLS support is implemented via external libraries. `Client::connect` and `Config::connect` take a TLS implementation
//! as an argument. The `NoTls` type in this crate can be used when TLS is not required. Otherwise, the
//! `postgres-openssl` and `postgres-native-tls` crates provide implementations backed by the `openssl` and `native-tls`
//! crates, respectively.
//!
//! # Features
//!
//! The following features can be enabled from `Cargo.toml`:
//!
//! | Feature | Description | Extra dependencies | Default |
//! | ------- | ----------- | ------------------ | ------- |
//! | `with-bit-vec-0_6` | Enable support for the `bit-vec` crate. | [bit-vec](https://crates.io/crates/bit-vec) 0.6 | no |
