Hello,
I discussed my problem at www.pg-forum.de with Mr. Scherbaum (ADS) and he recommended me to inform you about this
problem.
I worked on my Mac-Book (Mac OS X 10.6.6) with postgresql database version 9 (postgresql-9.0.1-1-osx.dmg). After
installingand connecting my HUAWEI E122 data modem (net provider 3 (drei)), I have detected, that I could't connect to
database.
Disconnecting the HUAWEI modem has no effects. I could not connect to database. Restarting the system makes the
databaseavailable again.
The problem occurs exactly at connecting to internet from 3DataManager. There are no problems with connecting USB-Stick
toMac Book or starting the 3DataManager.
I installed the postgresql-database with default settings:
host: localhost
port: 5432
user: postgres
listen_addresses: *
This is a netstat-result after connecting via HUAWEI data modem:
Active Internet connections (including servers)
Proto Recv-Q Send-Q Local Address Foreign Address (state)

tcp4 0 0 .psf.ipp *.* LISTEN
tcp6 0 0 localhost.ipp *.* LISTEN
Trying to start a telnet-connection, the result was:
telnet 127.0.0.1 5432
Trying 127.0.0.1...
telnet: connect to address 127.0.0.1: Operation timed out
telnet: Unable to connect to remote host
As I had no idea, what the problem could be, I tried installing the latest version of postgresql
(postgresql-9.0.2-1-osx.dmg),maybe that this problem is fixed now.
But it has no effect.
Then I tried reproducing the problem on my Windows 7 system. I installed the HUAWEI data stick and connected it to the
internet.
I could connect to database without problems!! So I checked the version of postgresql on my windows system. The version
is8.4! (postgresql-8.4.2-1-windows.exe)
After uninstalling of postgresql 9 from my Mac Book and installing the latest 8.4 version (postgresql-8.4.6-1-osx.dmg),
theproblem was also solved.
Maybe that the problem is a 32/64 bit problem.
best regards,
