A StartupMessage whose options parameter contains an empty parameter name, such as \"-c=\", makes the ignore_startup_parameters list lookup loop forever. Because PgBouncer serves all clients from a single process, this saturates a CPU core and makes PgBouncer unresponsive to all clients until the process is restarted."
