+//! # Logical Session Management in PgDog
+//!
+//! PgDog hides your shard topology and presents a single Postgres endpoint.
+//!
+//! When the client issues session commands (e.g. `SET`), `LogicalSession` records
+//! them to facilitate the replication of each command to every true server's
+//! session before routing queries.
