//! PostgreSQL WHERE clause SQL generation.

//! `PostgresWhereGenerator` is a type alias for

/// # Example
///
/// ```rust
/// use fraiseql_db::postgres::PostgresWhereGenerator;
/// use fraiseql_db::{WhereClause, WhereOperator};
/// use serde_json::json;
///
/// let generator = PostgresWhereGenerator::postgres_new();
///
/// let clause = WhereClause::Field {
///     path: vec!["email".to_string()],
///     operator: WhereOperator::Icontains,
///     value: json!("example.com"),
/// };
///
/// let (sql, params) = generator.generate(&clause).expect("Failed to generate SQL");
/// // sql: "data->>'email' ILIKE '%' || $1 || '%'"
/// ```
