Yes, you need the WAL files.
Now I have two directly conflicting answers. You say the WAL files are needed even though the DB is shut off, and Payal Singh says I don't need the WAL files (but I don't think he cc'd the mailing list).
Why are the WAL files necessary if the DB is shut off? Why can't they just be erased?
It's a gigabyte of copying that I was hoping to avoid.
