pub fn copy_payload_files(from: &StoreDir, to: &StoreDir)Expand description
Copy the file-backed payloads one store directory holds into another.
A store is a directory, not a file: rows name payload files beside the
database, so a test that copies the database with VACUUM INTO and opens the
copy has to bring those files along, exactly as a device carries its whole
store directory rather than one file out of it.
