A PostgreSQL database and user can be created via the Members Control Panel.
To begin, choose the PostgreSQL option from the sidebar, then click the "Add a new item" button.
Fill in the name - which will be both the name of the database and the name of the user as well as the remaining details.
You'll notice that the connection details are provided. In the example below, the database host is psql002.mayfirst.cx
. That domain name will only be available from withint the May First network, not externally. Do no choose "localhost" when configuring your database, use a domain name in the format psqlNNN.mayfirst.cx
where NNN
is a number, as provided in the control panel.
