Awesome... no failures building and it worked as expected:
-[ RECORD 1 ]----+-----------
pid | 102570
datid | 16388
datname | fabrizio
relid | 16398
command | COPY FROM
type | FILE
bytes_processed | 1359675392
bytes_total | 2921579128
tuples_processed | 18605306
tuples_excluded | 0
tuples_skipped | 0
