Message DB was extracted from the Eventide Project to make it easier for users to write clients in the language of their choosing.
A complete user guide is available on the Eventide Project docs site:

This library is an NPM module package of the Message DB database for Postgres.
For more information, see:
https://github.com/message-db/message-db
npm install @eventide/message-dbRunning the database installation tool creates the database, schema, table, indexes, functions, views, types, a user role, and limit the user's privileges to the message store's public interface.
Note: Make sure that your default Postgres user has administrative privileges.
To execute the update script, navigate to the directory where the message-db module is installed and run the script:
install.shBy default, the database creation tool will create a database named message_store.
If you prefer either a different database name, you can override the name using the DATABASE_NAME environment variable.
