The following documentation comment has been logged on the website:
Page: https://www.postgresql.org/docs/11/client-authentication-problems.html
Description:
The article on authentication problems refers to "the log" and the "server
log" but lacks information on where to find that log or how to configure
it.
https://www.postgresql.org/docs/11/runtime-config-logging.html appears to be
the relevant page to link to.
But AFAICT the default log level/configuration does not cause the messages
described on this page to be logged. So additional information on minimal
log configuration is required.
