The following bug has been logged online:

Bug reference:      4142
Logged by:          Lee Ottaway
Email address:      lee@fusionsoftwareuk.co.uk
PostgreSQL version: 8.3.1
Operating system:   Vista
Description:        pg_dump will not work
Details:

I activate pg_dump from my application and pass it the following
parameters:

pg_dump --host="NameofPC" --port=5432 -U "admin" --compress=3 --format=c
--verbose --file="C:\ProgramData\Bridge-IT\backup.sql" "nameofdatabase"

This works perfectly on any Windows XP machine, however when I try it on a
Vista machine I get the following error:

Connection to database "nameofdatabase" failed: FATAL:  no_hba.conf entry
for host "fe80::e11a:753d:9916:1a28%8", user "admin", database
"nameofdatabase", SSL off

Now I know this related to IP addresses in some way, however I can connect
to the database perfectly on the Vista machine and from client machines
looking over the network, so how come everything can connect but pg_dump
can't??

I am using the following pg_hba.conf entries:

# IPv6 local connections:
host    all         all         ::1/128               md5
host    all         all         192.168.0.0      255.255.0.0      md5

Any ideas??

Thanks

You are using the hostname, which means it will connect with the
machines "real" IP address (in this case, ipv6 address). You're not
making a local connection. Try --host=localhost instead, that should
make it use the loopback IP address (either V4 or V6, not sure which one
Vista will pick for you, but it shouldn't matter)

Your other option is to add the ipv6 address of the machine to the
pg_hba file, of course.
