I'm hoping I'm posting this to the right place.

I've been using PostgreSQL for a couple of years now. I'm successfully
running several PG servers at work for Data Warehousing and one at home for
various things (drupal, amarok, development)

I've decided to experiment with Visual Basic and PostgreSQL as there's
something I want to develop where I think VB would be best (mainly because
the only other languages I know are PHP and PICK)

My problem is, I use the connection string below to connect to the server at
work, and it connects fine; I can execute SELECT queries etc:
	strPG = "Driver={PostgreSQL};" & _
            "Server=sql.weatherbeeta.com.au;" & _
            "PORT=5432;" & _
            "Database=dwh;" & _
            "UID=postgres;" & _
            "PWD=thisisnotreallymypassword"

But when I take the same string and modify it to connect to my home server
(via VPN) it fails:
	strPG = "Driver={PostgreSQL};" & _
            "Server=192.168.1.234;" & _
            "PORT=5432;" & _
            "Database=develop;" & _
            "UID=postgres;" & _
            "PWD=anotherpassword"

The error message in VB is:
	"The database does not exist on the server or user authentication
failed."

The logs on my home server say:
2007-11-12 17:38:22 ESTLOG:  connection received: host=172.20.0.155
port=1148
2007-11-12 17:38:22 ESTLOG:  connection authorized: user=postgres
database=develop
2007-11-12 17:38:22 ESTLOG:  duration: 0.173 ms
2007-11-12 17:38:22 ESTLOG:  disconnection: session time: 0:00:00.142
user=postgres database=develop host=172.20.0.155 port=1148

I can connect using the same credentials via psql running on one of my
servers at work fine (172.20.0.155 is my work IP address), so it doesn't
appear to be incorrect username / password or firewall etc.

My only thought is that I'm using the wrong auth type in pg_hba, but they're
both the same at work and at home (md5)

Anyone help me or point me in the right direction?

Both servers are v8.2 under Linux; work one is 64-bit and home is 32-bit.

Cheers,
