For creating a database from code, I use the client instead of pool for this one. Here's the example:
const { Pool, Client } = require('pg')
const client = new Client({
user: 'postgres',
host: 'localhost',
password: 'postgres',
port: 5432
})
await client.connect()
await client.query(`DROP DATABASE IF EXISTS ${dbname};`)
await client.query(`CREATE DATABASE ${dbname};`)
await client.end()
//call the pool you just created after the database has been created.

Maybe the following code will help you. The table will now be created in the callback immediately after the "CREATE DATABASE" query has finished.
function createDatabase(){
const pool = new pg.Pool({
user: 'postgres',
host: '127.0.0.1',
database: 'postgres',
password: 'postgres',
port: '5432'}
);
pool.query("CREATE DATABASE myApp;", (err, res) => {
console.log(err, res);
pool.query("CREATE TABLE session(sessionguid UUID NOT NULL, created text NOT NULL, sessionlife integer NOT NULL)", (err, res) => {
console.log(err, res);
pool.end();
});
});

How can I create a table using Node.js?
I would create a Postgres function that creates the table. You can then call the function as a Supabase RPC. I haven't done this, but unless Supabase went to extraordinary lengths to prevent this sort of thing, it should work. https://dba.stackexchange.com/questions/42924/postgresql-function-to-create-table https://supabase.com/docs/reference/javascript/rpc More on reddit.com

The JS API that Supabase provides for interacting with the database does not support table creation. You don't have to use the dashboard however. You can create a .sql migration file and then apply it to the database (see the docs here: https://supabase.com/docs/reference/cli/supabase-db-push )

As you see it is a really easy process, however, the driver implementation requires to have a database name postgres://username:password@host/database to be connected, which means you need to connect to a database first.
It's not because of the driver implementation, it's PostgreSQL itself. It's the same with any other language or driver.
A client needs to be connected to a database in order to do anything, including a CREATE DATABASE. Besides the postgres database, template1 is often used for this purpose too.
Then, since you must connect to the freshly created database to create objects inside it, there's no way to avoid opening another connection.
In short, what you're doing can't be simplified, it's already optimal.

I've just written a module for that: https://github.com/olalonde/pgtools
var pgtools = require('pgtools');
pgtools.createdb({
user: 'postgres',
password: 'some pass',
port: 5432,
host: 'localhost'
}, 'test-db', function (err, res) {
if (err) {
console.error(err);
process.exit(-1);
}
console.log(res);
});
Hopefully it can make your code a bit cleaner.

Now, this should give us the output CREATE TABLE,but if you want to list all tables in a database, you shoulduse the dt command. For the sake of this example, we are going to add a row to the table so that we have some data to play with and prove that this works. When you want to add something to a database in PostgreSQL, you use the INSERT command.
