I can understand that the host is not available in nslookup, but why is
the user not being recorded?
A quick look at the source shows that Postgres system process can have NULL
username:
Well, the real point is that that message comes out before we've collected
the startup packet, so we don't *have* a username yet. All we know is
that somebody's opened a TCP connection. The later "connection
authorized" message will tell you what database user name they gave.
Eventually got around to figuring that. So just for my reference, the
code snippet I showed from postinit.c seems to show a path where a
username is not used but is substituted with BOOTSTRAP_SUPERUSERID.
Am I following that correctly and what is BOOTSTRAP_SUPERUSERID?
If you see lots more "connection received" than "connection authorized"
then somebody is connecting to your postmaster and failing to
authenticate, which is usually a good thing to investigate.
