Well it is using libpq for authentication on 09.03.0400, which is the
part that is going to throw the errors.
Also psql, which uses libpq does this:
aklaver@panda:~> psql -d test -U aklaver -W -h host
Password for user aklaver:
psql: could not translate host name "host" to address: Name or service
not known
aklaver@panda:~> psql -d test -U aklaver -W -h localhost
Password for user aklaver:
psql: FATAL: password authentication failed for user "aklaver"
FATAL: password authentication failed for user "aklaver"
So I am thinking this not a libpq issue, but a change in error reporting
when the code was reorganized in 09.05.0100. I do not know the internals
well enough to say anything more. Hopefully someone that does can fill
in the blanks.
