Migration hangs with "Currently creating table: `undefined`"

Great project! Thank you for creating this. I struggled with pgloader for too long before giving up and looking for something new.

I'm on MySQL 8.0.42 migrating to Postgres 17 and when I run npm start I get the following error:

Unfortunately it doesn't stop with an error or anything. If I look in the DB, the only tables created start with "data_pool" and "state_logs".

I've created PR #145. This fixes the problem of the relation name being lowercase (I'm guessing this is different in newer versions of MySQL?).

This fixed the problem for me.
