In GitHub actions, I am running a JavaScript file which connects to PostgreSQL and creates the table and extension for the database.
my script looks like this:
const { Client } = require('pg')
const pgclient = new Client({
host: process.env.POSTGRES_HOST,
port: process.env.POSTGRES_PORT,
user: process.env.POSTGRES_USER,
password: process.env.POSTGRES_PASSWORD,
database: process.env.POSTGRES_DB,
})
pgclient.connect()
const createDB = `
drop database mydb;
create database mydb;
\c mydb;
CREATE EXTENSION "pgcrypto";
`
pgclient.query(createDB, (err, res) => {
if (err) throw err
pgclient.end()
})
When I run the script, I get an error
error: syntax error at or near "c"
Which I am guessing is coming from \c
flag.
How do I use PostgreSQL commands like this?
you can not use \c here because it is a psql meta-command, which I think you do not use here: See https://www.postgresql.org/docs/current/app-psql.html .
You need to reconnect to the new DB like so:
const pgclient_mydb = new Client({
host: process.env.POSTGRES_HOST,
port: process.env.POSTGRES_PORT,
user: process.env.POSTGRES_USER,
password: process.env.POSTGRES_PASSWORD,
database: 'mydb',
})
pgclient_mydb.connect()
