//! Provides types and functions related to working with PostgreSQL
//!
//! Much of this module is re-exported from database agnostic locations.
//! However, if you are writing code specifically to extend Diesel on
//! PostgreSQL, you may need to work with this module directly.

pub mod types;

/// Data structures for PG types which have no corresponding Rust type
///
/// Most of these types are used to implement `ToSql` and `FromSql` for higher
/// level types.
