//! The SQLSTATE codes PostgreSQL defines, as listed in
//! [its documentation](https://www.postgresql.org/docs/current/errcodes-appendix.html)
//! and taken from
//! [`errcodes.txt`](https://github.com/postgres/postgres/blob/REL_18_0/src/backend/utils/errcodes.txt).
//!
//! Each constant is named after PostgreSQL's `ERRCODE_` macro and documented
//! with its PL/pgSQL condition name.
//!
//! ```rust
//! use diesel::pg::sql_state;
