Disclaimer: enabling remote access to the postgresql database is a security risk.

In general, it is not recommended to enable remote access to the Postgresql database used in kDB. But this can be necesserary for debugging purposes, especially if the database is running on a headless computer. First, initialise the store (for more information check the getting started tutorial).

# The following will create a PostgreSQL database in 'path/to/' using
# the default port 1242:
kdb store --path path/to/
# Use Ctrl+C to stop the store.

Then open the file path/to/postgresql.conf and add the following at the end:

listen_addresses = '*'

Then open the file path/to/pg_hba.conf and add the following at the end:

host    all             all             0.0.0.0/0            trust

Then restart the store. And you can now create remote connection to the Postgresql database:

  • #include <kDB/Repository/Connection.h>

// If the database is remote, the same method for creating the connection can be used,
// for instance:
kDB::Repository::Connection connection = kDB::Repository::Connection::create("127.0.0.1", 1242);

// Once a connection is created, it is required to connect
// to a database with:
connection.connect();

  • from kDB.Repository import Connection

# If the database is remote, the same method for creating the connection can be used,
# for instance:
connection = Connection.create("127.0.0.1", 1242);

# Once a connection is created, it is required to connect to a database with:
connection.connect();

  • require 'kDB/Repository'

# If the database is remote, the same method for creating the connection can be used,
# for instance:
connection = KDB::Repository::Connection.create "127.0.0.1", 1242

# Once a connection is created, it is required to connect to a database with:
connection.connect;

  • No connection object is needed for the command line.
