Access to database denied :ELEPHANTSQL on Bluemix - “No pg_hba.conf entry for host localhost, user ADMIN, database SYSTEM”
The error message means you are already accessing pg_hba.conf. There is just no line granting access for your connection attempt. At least one of your provided details (host, user, database) does not match for any line in the file.

I am not familiar with ElephantSQL, but it seems to be a database hosting service providing standard PostgreSQL. Advice in the manual should apply. Here is a related answer with more explanation and links:
