• What version of PostgreSQL is supported?
• Which PostgreSQL hosting provider is supported?

PostgreSQL v9.5 or later.

You can verify a potential hosting provider by running the EventStore test suite against an instance of the hosted PostgreSQL database. If all tests pass, then you should be fine.

To run the test suite you must first clone this GitHub repository:

git clone https://github.com/commanded/eventstore.git
cd eventstore
mix deps.get

Then configure your database connection settings for the test environment, in config/test.exs.

Once configured, you can create the test database and run the tests:

MIX_ENV=test mix do event_store.create, event_store.init
mix test
