1//! `PostgreSQL` types.
2//!
3//! - [`types`]: zero-sized SQL type markers used for compile-time checks.
4//! - [`PostgreSQLType`]: column types as written in DDL, with their metadata.
5//! - [`TypeCategory`]: how a Rust field type maps to a `PostgreSQL` column.
6//! - [`PgTypeCategory`]: categories of SQL type names, used when parsing.
7//! - [`ddl`]: schema objects (tables, columns, indexes, ...) for migrations.

13/// Zero-sized SQL type markers for the `PostgreSQL` dialect.
14///
15/// Each marker stands for one SQL type at compile time; it carries no length,
16/// precision or enum values (see [`PostgreSQLType`] for those). The traits in
17/// [`crate::sql`] say which markers can be compared, assigned, or used in
18/// arithmetic. The Rust types listed are the default value mappings.
