trait BufferedMessageSocket[F[_]] extends MessageSocket[F]

A MessageSocket that buffers incoming messages, removing and handling asynchronous back-end messages. This splits the protocol into a [logically] synchronous message exchange plus a set of out-of-band broadcast channels that can be observed or ignored at the user's discretion.

Stream of all channel notifications that this Session is subscribed to.

Stream of all channel notifications that this Session is subscribed to. Note that once such a stream is started it is important to consume all notifications as quickly as possible to avoid blocking message processing for other operations on the Session (although typically a dedicated Session will receive channel notifications so this won't be an issue).

Value parameters

maxQueued: the maximum number of notifications to hold in a queue before [semantically] blocking message exchange on the controlling Session.

Signal representing the current state of all Postgres configuration variables announced to this session.

Signal representing the current state of all Postgres configuration variables announced to this session. These are sent after authentication and are updated asynchronously if the runtime environment changes. The current keys are as follows (with example values), but these may change with future releases so you should be prepared to handle unexpected ones.

Map(
 "application_name"            -> "",
 "client_encoding"             -> "UTF8",
 "DateStyle"                   -> "ISO, MDY",
 "integer_datetimes"           -> "on",       // cannot change after startup

Signal broadcasting the current TransactionStatus which is reported after each completed message exchange.

Signal broadcasting the current TransactionStatus which is reported after each completed message exchange. Note that this value may be stale in the case of a raised exception, which should prompt the front end to send a Sync message but currently does not.
