Обсуждение: pg_dump on remote machine

Hello,
Iam trying to take a dump of my DB from one machine to another in this
fashion:

on the secondary database:

pg_dump -b -h 172.16.1.20 (dbname) > /tmp/dump.dump

my error is :
could not connect to database etc...etc..

although the file dump.dump in /tmp is created.(it's empty)

I can access remote database on my secondary through phpPgAdmin.

Any clues??

I have used pgadmin III to do that so you may want to try it.

TIP 6: Have you searched our list archives?

               http://archives.postgresql.org

Check the pg_hba.conf file to see if you have access to the database, as
user that you are trying to connect as, from the IP you are trying to
connect from.
I'll bet that you don't.  Check you postgres error logs, and you should
see the refused connection.  You might have to tweak the logging settings.

Also, the exact error you get would be a bit more helpful.

Can you get connect with
psql -h 172.16.1.20 (dbname)


I think, you /etc/pg_hba.conf must be configured to grant this access.
And don't forget to reload the postmaster after this.

Look in the log of postgresql.

Hello,

> Yes I can get connected by psql -h 172.16.30.2 (dbname) and I can also connect
to the remote DB using phpPgAdmin. I have given the permissions on
pg_hba.conf file.

Hmmm,
when you connected with psql -h 172.16.30.2 (dbname),
are you able to get data with the select-command?
If not, you must grant access with the grant-command.

And you should look to the logfile of postgresql.
