Re: Problems using PostgreSQL command line tools - Mailing list pgsql-novice

Hi, thank you for the answer. However it's not very useful to me:

C:\>psql -h 127.0.0.1 -U postgres -d postgres
psql: FATAL:  password authentication failed for user "postgres"

My main question is: given the command line

   psql -h localhost -U postgres -d postgres

why at home is ok (and works without problems) and at office doesn't
work at all???

pg_hba.conf contains:

# TYPE  DATABASE    USER        CIDR-ADDRESS          METHOD

# IPv4 local connections:
host    all         all         127.0.0.1/32          md5
# IPv6 local connections:
#host    all         all         ::1/128               md5

on both computers.

Regards.
Andrea
