F.3. auth_delay

F.3.1. Configuration Parameters
F.3.2. Author

+ auth_delay causes the server to pause briefly before + reporting authentication failure, to make brute-force attacks on database + passwords more difficult. Note that it does nothing to prevent + denial-of-service attacks, and may even exacerbate them, since processes + that are waiting before reporting authentication failure will still consume + connection slots. +

+ In order to function, this module must be loaded via + shared_preload_libraries in postgresql.conf. +

F.3.1. Configuration Parameters

+ auth_delay.milliseconds (integer) + +

+ The number of milliseconds to wait before reporting an authentication + failure. The default is 0. +

+ These parameters must be set in postgresql.conf. + Typical usage might be: + 

+# postgresql.conf
+shared_preload_libraries = 'auth_delay'
+
+auth_delay.milliseconds = '500'
