This seems to be caused by psql sending the comment to the server to
evaluate as a query. I personally think timing should always output
something for every command sent to the server. To fix this problem I
guess one would have to modify psql_scan() to check if a scanned query
only contains comments and then not send it to the server at all.
The minimal file to reproduce it is:
