![]() ![]() There are no guarantees about queries executing in order unless using a transaction with sql.begin() or setting max: 1. Use ‘’ to listen on all interfaces on the host. listenaddresses option to control the interface where the port will be listening. Thus, the simplest way to start the server is: postgres -D /usr/local/pgsql/data. ![]() The postgres program must know where to find the data it is supposed to use. The database server program is called postgres. The default port number is 5432 but you can change it as required. Before anyone can access the database, you must start the database server. The benefit of this is no weird generic "onerror" handler that tries to get things back to normal, and also simpler application code since you don't have to handle errors out of context. The port option sets the PostgreSQL server port number that will be used when listening for TCP/ IP connections. It'll automatically defer to the error handling you have for that query, and since connections are lazy it'll automatically try to reconnect the next time a query is made. Connections are automatically taken out of the pool if you start a transaction using sql.begin(), and automatically returned to the pool once your transaction is done.Īny query which was already sent over the wire will be rejected if the connection is lost. Queries will be sent over the wire immediately on the next available connection in the pool. This means that we get a much simpler story for error handling and reconnections. users.js import sql from './db.js' async function getUsersOver ( age ) ). ![]()
