Unable to run `mix event_store.init` with existing database

[slashdotdash]

This is due to a clash between the table used by Ecto and EventStore to manage their database migrations. Both use the same schema_migrations table name.

You will need to either:

• Rename the existing Ecto schema_migrations table to prevent the conflict. See #73 for details.
• Use a separate Postgres schema or database for the event store.
• Submit a PR to allow the EventStore migrations table to be configured (😉)

Thanks for the info!

I tried to make the table configurable. Please have a look at the diff here: develop...ser1us:feature/configure-migration-source

1. Not sure if there is a better way to interpolate the database name into the create and insert script
2. I would need some help with some tests :) The tests are working fine, which means the method returns the previous name as the fallback. But I guess it would be good to have some explicit tests in place.
3. Last but not least, there is no documentation yet 😂

I would love to get some early feedback before I finish the work and submit a PR.

I was able to execute event_source.init in my project with this change and adjusted config. The table is created and everything is set up.

Cheers!
