示例1: Client
.then((location) => {
let client = new Client({
host: location.hostname,
port: location.port || 5432,
database: database,
user: user,
password: password,
parseInputDatesAsUTC: true // not in the type
} as any);
client.on('drain', client.end.bind(client)); // disconnect client when all queries are finished
client.connect();
//query is executed once connection is established and PostgreSQL server is ready for a query
let q = client.query(new (Query as any)(query) as any);
// ToDo: use node-pg-cursor or node-pg-query-stream here instead
q.on('row', function(row: any) {
stream.push(row);
});
q.on('error', function(err: any) {
stream.emit('error', err); // Pass on any errors
});
q.on('end', function() {
stream.push(null); // pushing null, indicating EOF
});
