     Each connection to :memory: opens a brand new in-memory sql database, so if
     the stdlib's sql engine happens to open another connection and you've only
     specified ":memory:", that connection will see a brand new database. A

Make sure the [max idle connection limit](https://golang.org/pkg/database/sql/#DB.SetMaxIdleConns) is > 0, and the [connection lifetime](https://golang.org/pkg/database/sql/#DB.SetConnMaxLifetime) is infinite.
