A Few Small Updates to Message DB

Message DB was released last week after incubating for three years in the Eventide Project as its message store implementation.

There were a number of significant changes made to the implementation in the transition from its life as Eventide’s Postgres Message Store (formerly evt-message_store-postgres-database) to its existence as a standalone project.

As existing users started getting hands-on with the new implementation and upgrading their databases to Message DB v1, a couple of bloopers were spotted.

A handful of small updates were made this week. Here are the details:
