We most certainly do print something --- in your example I get this:
LOG: invalid authentication method "127.0.0.1"
CONTEXT: line 81 of configuration file "/home/postgres/data/pg_hba.conf"
FATAL: could not load pg_hba.conf
I suspect you are using a configuration that redirects the postmaster's
log to /dev/null, or some equally unhelpful place :-(.
FWIW, this message comes out after the logging settings in
postgresql.conf have been adopted, so you should look to those to see
where the message actually went. Errors in postgresql.conf itself
typically get reported on postmaster's stderr.
