If I have a table which has been fully refreshed and I need to add a column, do I need to truncate and refill the table, or will passing a --full-refresh flag upsert/merge that column into the table automatically based on the PK?

It depends on the target, but yeah most of them should automatically add the new column, and doing the full-refresh should backfill that column.

Awesome - thank you!
