What I need to know if I use service to create PostgreSQL in Heroku, can I set up this database locally in development mode?
I couldn't find in their documentation on how to do this.

Please I need your help.
I have a Django app that is running on heroku.
The Django app initially uses an sqlite3 database.
The local and the remote versions of the app worked fine.
I could access the sqlite3 database on my local machine. However, I have no idea, e.g. an interface, through which I could access the database version that is running on heroku.
Then, I changed the database to Postgresql.
The local version of the database worked fine with the application, as I could see the data being written into the local posgresql whenever I have a need to check the data in the database.
However, I need to be able to see how data is being written into the remote postgresql.
When I try to connect to the database on postgresql, I get an error as shown in the snapshot below.
Please, how can I connect to the database on heroku and see my database.
I am currently using a free heroku account. I hope that is also not a problem?

Most of the documentation Ive seen only covers using mLab as a service for mongodb on heroku,
I would like to use mongoDB locally on the heroku server is this possible?
Heroku dynos use an ephemeral filesystem. This means that you cannot run a database on a Heroku dyno. All of the data will be lost whenever your process restarts. Your process restarts at least once every day, whenever you deploy new code, whenever you change config variables, or whenever you update add-ons.
You can read more about Heroku's ephemeral filesystem here: https://devcenter.heroku.com/articles/dynos#ephemeral-filesystem
You can read more about dyno restarts here: https://devcenter.heroku.com/articles/dynos#restarting
So you will have to use a Heroku Add-on or a third-party service to add persistence to your application.
This doesn't mean you have to use the mLab Add-on. If you have your own MongoDB database, you can still connect to that in your application. You can add the connection string as a config variable and connect to it in the same way you would connect to an mLab Add-on.
I have deployed my SpringBoot app to Heroku. Now I would like to copy my local PostgreSQL to Heroku.
I have found some information on devcenter.heroku.com.
However I don't understand enough about the using of file db.changelog-master.yaml.
Could anyone give me details about the simplest solutions to copy the database?
Create a valid dump of your local postgres database and host it somewhere publicly available. Now you will be able to restore this entire dataset (schema and records) with pg:backups:restore as shown here. The sole caveat here is that the target database must be completely empty for this to work. You can empty a Heroku postgres database with heroku pg:reset.
If you cannot take the approach listed above then you can run pg_restore directly from your local instance, provided your local version of Postgres is >= the target version of Postgres. This also applies to creating the dumpfile and is a requirement because pg utilities are not guaranteed to be forward compatible. Documentation for pg_restore is here.
My understanding is that Heroku Postgres runs on top of AWS. Is it possible to configure which datacenter your database is running in? I'm also wondering if the database files are stored on an encrypted filesystem.
Yes, Heroku runs on AWS. But you are not able to specify which datacenter to run your database. For encryption look at http://www.postgresql.org/docs/current/static/pgcrypto.html.
Heroku runs out of Amazon US-East - once you've add a postgres db to your app heroku config will give you the database connection URL which you would be able to tracert on to see where it is
I have pulled the SHARED_DATABASE_URL from heroku config
SHARED_DATABASE_URL => postgres://username:xxxx#host.com/db_name
I am using pgAdmin to try to connect to it but it keeps on timing out. Do I need to specify a port? What am i missing?
You can use this command to connect to psql.
heroku pg:psql
If you are happy to change to postgres 9.1 you can use the newly launched development database, which permits connections via normal postgres tools. Read more at https://postgres.heroku.com/blog/past/2012/4/26/heroku_postgres_development_plan/
You cannot access the shared database using psql, pgadmin, etc.
Heroku offers you the choice of running on a shared or dedicated database package. The shared plan is suitable for development and staging applications. It runs Postgres 8.3. The dedicated plans are suitable for production scale applications. In addition, the dedicated databases offer a number of advantages, including direct access (via psql or any native postgres library), stored procedures, and Postgres 9 support.[source]
