Hello -
I'm running PG 8.1 on Windows XP.
I've installed the server to run as a service.
The psql command fails to connect to the server, although I can connect with other clients.
When I enter psql -d mydb -h localhost -U admin
I get the following response:
psql: could not connect to server: Connection refused (0x0000274D/10061)
Is the server running on host "localhost" and accepting
TCP/IP connections on port 5432?
However, with the following steps I can prove that the server is indeed running on localhost and listening on 5432.
First, I run pgAdmin3 and connect to the server. The properties panel shows me that I'm connected to the server via localhost port 5432.
Next, with pgAdmin3 running, I do a netstat and get the following result:
TCP jma:1500 localhost:5432 ESTABLISHED
TCP jma:1502 localhost:5432 ESTABLISHED
TCP jma:5432 localhost:1500 ESTABLISHED
TCP jma:5432 localhost:1502 ESTABLISHED
But if I now run psql, I get the same error message as before.
My postgresql.conf file has the following line:
listen_addresse s = 'localhost'
I also tried changed 'localhost' to '*', but the result was the same.
If I leave off the -h option on the psql command, the message is a little different. It says (in part):
... Is the server running on host "???" ...
I've searched the threads in this forum for psql problems and found a few. But not exactly this one.
Can anyone tell me why psql won't connect?

We may need to look at postgresql.conf and pg_hba.conf, but before we get to it, are you running a firewall on this computer?
If yes, could you try to disable it for a minute and run psql again?
Thank you. It was my Zone Alarm firewall. I turned it off, and it worked.
I originally thought that the firewall was not the problem, because it was letting the other clients connect.
Strange thing though --- when I turned ZA back on, it let psql run. I found that it had created a rule saying psql was OK. bizarre.

Yes, ZoneAlarm can be tricky. If I remember correctly there could be different ways to allow your programs to work, you can open the specific port#, or you can designate a certain app as trusted... Anyway, the good thing is you got it working!

Hi All,
Took a break from developing on pgsql 7.3 to set up network printing
where I added another host(localhost 193.168.1.2) in red hat network
settings. Later, I could start postmaster but when I started psql I got
the following error when I issue this command:
psql -h localhost -U postgres nba

Hello all,
I just wanted to pass on some information about compatibility between
the psql client and the postgres server.
On a particular network, my workstation and the server are both debian
boxes, but the workstation is on a more frequent upgrade schedule. The
server is still running postgres 7.3.4, but my workstation has been
upgraded with the latest (7.4.1) postgres client tools.

Hi everyone.
I'm searching for a quick and dirty way to have psql record the
SQL statements that I enter, especially those related to the database
structure.
My main motivation is to help keep what will probably be a production
server up-to-date with my development server. I've thought a little
about replication, but the current options for that seem like overkill
for the relatively small database that I have. I'm particularly

With the advent of postgres v8, would it be possible to change the
default behaviour of psql from AUTOCOMMIT=ON to AUTOCOMMIT=OFF ?
Although this might break backward compatibility, it might be acceptable
on the basis that v8 is such a major release.
Also adding a new command line parameter to control the AUTOCOMMIT
setting for those users that will experience broken scripts executed
(especially using the -c command) might help ease...

I've got a postgres db running on a windows mc. I've set it up to accept remote connections. Can I use psql from another machine (*nix) to connect to it?
I've tried this: psql MYDB -U postgres -h 192.168.1.20 but I get the error missing or erroneous pg_hba.conf file which I don't understand.
The pg_hba.conf file is a configuration file residing on the host, isn't it? Why is the client asking for it?

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
