//! Athena router data access.
//!
//! This module provides functions for accessing Athena router entries stored in the
//! `athena_logging` Postgres client. Router entries define routing configurations
//! used by the Athena system.

use sqlx::Row;
use sqlx::postgres::{PgPool, PgRow};
use sqlx::types::JsonValue;

/// Fetch all Athena router entries from `athena_logging`.
///
/// Retrieves all router entries from the `pm_athena_router` table.
///
/// # Returns
///
/// Returns `Result<Vec<Value>, String>` where:
/// - `Ok(Vec<Value>)` contains the list of router entries on success
/// - `Err(String)` contains a formatted error message on failure
///
/// # Example
///
/// ```ignore
/// # use sqlx::postgres::PgPool;
/// # async fn demo(pool: &PgPool) {
/// match list_athena_router_entries(pool).await {
///     Ok(entries) => println!("Found {} entries", entries.len()),
///     Err(e) => eprintln!("Error: {}", e),
/// }
/// # }
/// ```
