How to allow remote access to PostgreSQL database?
In order to remotely access a PostgreSQL database, you must set the two main PostgreSQL configuration files: Here is a brief description about how you can set them (note that the following description is purely indicative: To configure a machine safely, you must be familiar with all the parameters and their meanings)
How can I change the default settings in PostgreSQL?
If your PostgreSQL database is installed on a separate server, you need to change the default settings in the postgresql.conf and pg_hba.conf files in the remote database. Change the listening address in the postgresql.conf file. By default, PostgreSQL allows to listen for the localhost connection. It does not allow a remote TCP/IP connection.
How to check database query string in PostgreSQL?
After running dblink_exec (), you can check the results in the remote database (or locally, using dblink (), like in the example below). As you can see, you can even build your query string dynamically. (Not that I advocate this approach, since you have to be careful not to introduce a SQL injection vulnerability into your system this way.)
Why does PostgreSQL not allow TCP / IP connection?
When you install PostgreSQL, by default connection to the database using TCP/IP is not allowed. When you try to connect from a client to a remote PostgreSQL database using psql command, you might get “psql: could not connect to server: Connection refused” error message.
Which is the default logging parameter in PostgreSQL?
The default is to log to stderr only. This parameter can only be set in the postgresql.conf file or on the server command line. If csvlog is included in log_destination, log entries are output in “comma separated value” ( CSV ) format, which is convenient for loading logs into programs.
Where do I set the default program name in PostgreSQL?
This parameter can only be set in the postgresql.conf file or on the server command line. When logging to syslog is enabled, this parameter determines the program name used to identify PostgreSQL messages in syslog logs. The default is postgres. This parameter can only be set in the postgresql.conf file or on the server command line.
How to connect to IP port in PostgreSQL?
Following configuration only required for PostgreSQL version 7.x or older. Open config file, enter: # vi /var/lib/pgsql/data/postgresql.conf. Bind and open TCP/IP port by setting tcpip_socket to true. Set / modify tcpip_socket to true: tcpip_socket = true. Save and close the file.
Where can I find configuration file for PostgreSQL?
You need to open PostgreSQL configuration file /var/lib/pgsql/data/postgresql.conf or /etc/postgresql/8.2/main/postgresql.conf. Find configuration line that read as follows: Next set IP address(es) to listen on; you can use comma-separated list of addresses; defaults to ‘localhost’, and ‘*’ is all ip address:
