Metadata about an active connection.

Fields§

§secret_key: u32

Pgwire specifies that every connection have a 32-bit secret associated with it, that is known to both the client and the server. Cancellation requests are required to authenticate with the secret of the connection that they are targeting.

§connected_at: EpochMillis

The time when the session’s connection was initiated.

§user: User§application_name: String§uuid: Uuid§conn_id: ConnectionId§client_ip: Option<IpAddr>§drop_sinks: BTreeSet<GlobalId>

Sinks that will need to be dropped when the current transaction, if any, is cleared.

§deferred_lock: Option<OwnedMutexGuard<()>>

Lock for the Coordinator’s deferred statements that is dropped on transaction clear.

§pending_cluster_alters: BTreeSet<ClusterId>

Cluster reconfigurations that will need to be cleaned up when the current transaction is cleared

§notice_tx: UnboundedSender<AdapterNotice>

Channel on which to send notices to a session.

§authenticated_role: RoleId

The role that initiated the database context. Fixed for the duration of the connection. WARNING: This role reference is not updated when the role is dropped. Consumers should not assume that this role exist.
