I'm trying to perform a relatively trivial task: I want to connect to a Heroku database. I have created the database and have been issued credentials from the Heroku site. However, when I try to connect to this database using anything besides the terminal 'heroku' command line client, I get fatal errors or cannot connect errors.

The two tools that I tried to connect with outside of the Heroku terminal application are: Navicat and IntelliJ.

The error that I receive in Navicat when trying to connect to the database is:

could not connect to server: Host is down
    Is the server running on host "ec2-107-21-112-215.compute-1.amazonaws.com" and accepting
    TCP/IP connections on port 5432?

My connection settings are as follows:

Connection Name Heroku Dev Test

Host Name/IP Address ec2-107-21-112-215.compute-1.amazonaws.com

Port 5432

Navicat doesn't even seem to be making an attempt to connect to that hostname.

When I try to connect with IntelliJ, using the full credentials, I get the following error:

java.sql.SQLException: FATAL: no pg_hba.conf entry for host "75.168.4.146", user "rphbqggxeokuxl", database "dc008iqk0rq4j5", SSL off

Again, I'm using the credentials that the Heroku application provides me with when accessing my database on their website.

Has anyone ran into this Heroku connection issue before?

Heroku provides this information for connecting from external sources:

https://devcenter.heroku.com/articles/heroku-postgresql#external-connections-ingress

The second error message indicates PostgreSQL is not configured to accept the connection you're trying to make. Given the information Heroku provides, a good guess is that you're not connecting with SSL. Try to enable that on your connection.

Here are instructions for using SSL with Navicat: http://mirror.navicat.com/manual/online_manual/en/navicat/rv_manual/ClientCert.html.

This may be helpful in configuring Intellij to use SSL: https://devcenter.heroku.com/articles/connecting-to-relational-databases-on-heroku-with-java#connecting-to-a-database-remotely.

Connecting to Relational Databases on Heroku with Java, Most clients connect over SSL by default, but sometimes it's necessary to add the sslmode=require query parameter to your database URL before  Use of SSL is required for all database connections on Heroku Postgres. The default sslmode is set a small properties file that is automatically added to your classpath. You prevent this file from being injected by running heroku config:set SKIP_PGCONFIG_INSTALL=true. Drivers for other database vendors are unaffected.

I also had the issue with the FATAL: no pg_hba.conf entry for host error message.

I solved the connection issue to my Heroku Postgres database by adding the following to my JDBC string: &ssl=true&sslfactory=org.postgresql.ssl.NonValidatingFactory.

Example

jdbc:postgresql://host:port/database?user=username&password=secret&ssl=true&sslfactory=org.postgresql.ssl.NonValidatingFactory

You will need the SSL option only if SSL is enabled for your Postgres database (which is the default).

Hint

If you want to check your database connection properties, then just run the following command with the Heroku Toolbelt: heroku pg:info --app your-heroko-appname (make sure that you have Postgres insalled to run this command in your terminal)

The pg:info command will also tell you that sslmode is set to require.

To test the database connection I recommend SQL Power Architect as it is the tool which I was using to check my solution.

Heroku Postgres, Heroku Postgres Connection Pooling allows applications to make more cast the prepared_statements configuration string as a boolean. All Heroku Postgres databases have a corresponding Heroku application. You can find the application name on the database page at data.heroku.com. Your database is attached to the Heroku app and is accessible via an app config var containing the database URL, even if you host no code in the application itself.

Connecting to Heroku Postgres Databases from Outside of Heroku , yml to set any values found in ENV['DATABASE_URL'] . This is a list of attributes you cannot change: adapter; database; username; password  Connecting to a Private or Shield Heroku Postgres Database from an External Resource; Connecting to a Private or Shield Heroku Postgres Database via PrivateLink; Encrypting Heroku Postgres with Your Encryption Key; Postgres Basics; Postgres Performance; Postgres Data Transfer & Preservation; Postgres Availability; Postgres Special Topics

Wanted to help others who might run into this. If you're supplying the Username and Password in seperate fields rather than on the command line, you need to use a ? between the database name and ssl=true and discard the first &

jdbc:postgresql://host:port/database?ssl=true&sslfactory=org.postgresql.ssl.NonValidatingFactory

That's the command line that finally allowed me to connect to a PostgreSQL database using SQL Power Architect

Heroku Postgres Connection Pooling, Configuring database connections in the Active Record connection pool for apps Now you can set the connection pool size by setting a config var on Heroku. Every application will have different performance characteristics and different  Enter the connection properties. Connect to database: enter Database name from your database configuration screen on MSSQL add-on Dashboard. Figure 3. Connect to the database. Click on Login tab and then on the Connect button to connect to your database. Figure 4. Connected to database. If you are connected to the database, you will see the following screen indicating that the external connectivity to the database you created in MSSQL add-on is successful. Support

You may consider setting a ENVIRONMENT CONFIG VARIABLE 'PGSSLMODE' to 'require' via Heroku's web interface or CLI.

Case: Postgres dB set up as a Heroku add-on and attached to app on a Heroku Dyno.

Heroku's instructions unfortunately leave out any mention of how to activate SSL, even though it is required for any dB tier starting with Standard-0 by default.

Follow all of the pg-copy or pg-upgrade steps (preferred approach depends on your version of Postgres) in Heroku instructions; however, before decommissioning the old database (if relevant) -- add the PGSSLMODE environment variable.

The instructions sufficiently cover how to promote the new database (and, consequently set the DATABASE_URL), so no changes/modifications to them should be required.

Rails Database Connection Behavior, If you want to connect to Heroku Postgres, create a data source connection that settings, click the Advanced tab and change values of the following properties:. I am developing a simple PHP application running on Heroku. I have created a CSV file and am using it as a simple database. Now I want to create a database on Heroku, so I added a Postgres instance and its name is heroku-postgres-9f90a33a::ivory. I want to know how I can create and manage my database instance to perform actions like creating a

Concurrency and Database Connections in Ruby with ActiveRecord , I solved the connection issue to my Heroku Postgres database by adding the following to my JDBC string: &ssl=true&sslfactory=org.postgresql.ssl. Heroku Postgres is a managed SQL database service provided directly by Heroku. You can access a Heroku Postgres database from any language with a PostgreSQL driver, including all languages officially supported by Heroku.

  • If you are configuring access from RubyMine, here is more detail: stackoverflow.com/questions/20807272/…
  • Here is how you configure it for DbVisualizer: bartling.blogspot.com/2013/06/…
  • Edit your Connection URL and add: sslmode=require.
  • &ssl=true&sslfactory=org.postgresql.ssl.NonValidatingFactory adding this solved my problem. thank you.
  • Thank you so much #Benny. I was stuck from last two days and finally get resolved and I have also asked a question related to this on StackOverflow. (stackoverflow.com/q/50772559/7560986). You are most welcome on that also.
  • This helping me alot. Thank u :)
  • Since manually editing DATABASE_URL is not supported, the quickest way is to set PGSSLMODE=require in the environment variables. stackoverflow.com/a/47536752/152711
  • Why NonValidatingFactory? What are the security implications of not validating?
  • this works. The same properties apply in jetbrains DataGrip that i'm using.
  • Thanks, this was super helpful!
  • this worked for me, thanks so much!
