describeDatabase hangs

[spencerdcarlson]

dbdiff.describeDatabase(conn1) .then((schema) => { console.log(schema) })

prints the schema, but hangs in the terminal

That's because the connection is still alive. I'll check how the connection is handled and if necessary provide a way to close it or close it automatically.
