Expand description

PostgreSQL network (“wire”) protocol.

For brevity, we often refer to the protocol as “pgwire,” hence the name of this module. Beware that this name is only commonly used in the CockroachDB and Materialize ecosystems. The PostgreSQL documentation, for example, uses the long-winded “Frontend/Backend Protocol” title instead.
