Im trying to connect locally to a database on a running postgres
cluster. If i connect with psql, everything is fine and i can transact.
I i try and connect in my own app, i get this error:

Could not connect to server: permission denied.
Is the server running locally and accepting
connections on Unix domain socket "/tmp/.s.PGSQL.5432"

I know for a fact postgres is running, i can see with <ps> and also
<top> in the terminal on Mac OSX 10.3.5.

What exctly does this error message mean? What permissions is this
error talking about?

Alex

Try 'netstat -ntpl' intead to see if it's listening.

That typically means that you're connecting via the local unix socket
instead of the tcp port. If your application is trying to do the
latter you'll want to uncomment the tcp_socket setting in
postgresql.conf and restart.

The permissions on the socket file /tmp/.s.PGSQL.5432.

Ordinarily the postmaster will create the socket as world-writable,
but evidently not this time. Perhaps you have set a nonstandard value
for "unix_socket_permissions"? Another possibility is that it's not
the socket file itself, but /tmp that is mis-permissioned.

What kind of permissions does /tmp need?

Generally it's 777 (ie, wide open), plus stickybit if your system
supports that (so people can't delete each others' temp files).

Hi All,

I want to connect to PostgreSQL 7.4 from my Windows machine. What ODBC
version is needed? Is there any other important settings required? I am very
new to this database.

Thanks,
Astha

TIP 2: you can get off all lists at once with the unregister command
(send "unregister YourEmailAddressHere" to majordomo@postgresql.org)

Search on google: "odbc postgresql" and I'm feeling lucky.
