Execute two queries at the same time on psql with node postgres-CodePudding

I have two independent queries for example:

const query = "SELECT PG_SLEEP(30);"
const query1 = "SELECT PG_SLEEP(30);"

console.time("Query")
await Promise.all([pgClient.query(query), pgClient.query(query1)]);
console.timeEnd("Query")

This, according to the documentation, will be added to a queue and execute one after the other, is it possible to execute the two queries asynchronously? so the registered time should be around 30 instead of 60...

UPDATE: Other approach would be to use the pool feature of the library instead of instantiating two clients

CodePudding user response：

For that, you have to open two database connections. Then it is no problem to have two queries running concurrently.
