Q: I work behind a firewall (router). Can EMS Data Export connect to a remote PostgreSQL server?

A: If due to the security policy accepted in your corporate network or by your host provider you cannot connect to your PostgreSQL server directly through TCP/IP (for example a firewall prevents this), you can use SSH or HTTP tunneling feature of SQL Manager to fulfill your task.


Q: Why cannot I connect to PostgreSQL Server?

A: 1. Make sure that there is a record for your client PC in pg_hba.conf file on PostgreSQL server. This file can be found in database cluster's data directory.

2. If you connect to the remote server, then the TCP/IP connections should be allowed on the remote server. In this case you need to edit file postgresql.conf on the server: just add the name or TCP/IP of the client PC in the listen_addresses list. Or you can as well put * character; in this case the connection from any host will be allowed. You can get the same result if you run the server with -i option, which is the same as listen_addresses = '*'.

3. Make sure that you enter the correct login/password.

4. You use password authentication, but it is not supported in Data Export.
