Module types 

Zero-sized SQL type markers for the PostgreSQL dialect.

Each marker stands for one SQL type at compile time; it carries no length, precision or enum values (see PostgreSQLType for those). The traits in crate::sql say which markers can be compared, assigned, or used in arithmetic. The Rust types listed are the default value mappings.
