8.0.0beta1 tarball built with gcc 3.2.3 under Solaris 9 on a E250
(ultrasparc). I see the same bug as described in
http://archives.postgresql.org/pgsql-admin/2004-05/msg00248.php: a mask
of 255.255.255.255 in pg_hba.conf is rejected with
> LOG: invalid IP mask "255.255.255.255" in pg_hba.conf file line 65: host/servname not known
This also breaks in the same way (with a less useful error message)
under 7.4.3.
Per http://nagoya.apache.org/bugzilla/show_bug.cgi?id=20063, adding
'dns' to the hosts lookup order in /etc/nsswitch.conf fixes the problem,
as does using any other mask but 255.255.255.255.
Since the default config now allows TCP/IP connections from localhost,
maybe we should tweak the default pg_hba.conf to work around this
problem? (e.g. use the /32 syntax which works ok)
