Node.js, PostgreSQL error: no pg_hba.conf entry for host

I am following this article ((http://nodeexamples.com/2012/09/21/connecting-to-a-postgresql-database-from-node-js-using-the-pg-module/). I have already deployed my app to heroku and currently using express, node.js, to try and connect to a PostgresSQL database in Heroku that I just installed. I get to the very end of the article and I use the command 

node myfile.js

I get this error

error: no pg_hba.conf entry for host "...", user "...", database "...", ...

How do I go about creating one and where in my app directory should I put it?

Below is the entire error message. I changed the strings for IP address, user, and database but it looks basically just like it. 

events.js:72
    throw er; // Unhandled 'error' event
          ^
error: no pg_hba.conf entry for host "00.000.000.00", user "username", database "databasename", SSL off

Edit: I did some more research and found that the 'pg_hba.conf' file is in my 

/usr/local/var/postgres

and I added this line into the 'pg_hba.conf' file

# TYPE  DATABASE        USER            ADDRESS                 METHOD
 host   all             all                                     trust

also tried

# TYPE  DATABASE        USER            ADDRESS                 METHOD
host   all             all              0.0.0.0/0               md5

but it keeps saying there is no entry for my host, user, database, etc... is my 'pg_hba.conf' syntax wrong in any way?

Solution

  • Change your connection code to use ssl. Following your linked example:

    var conString = "pg://admin:guest@localhost:5432/Employees";
var client = new pg.Client(conString);
client.connect();

    becomes:

    var client = new pg.Client({
    user: "admin",
    password: "guest",
    database: "Employees",
    port: 5432,
    host: "localhost",
    ssl: true
}); 
client.connect();
