I removed it.
Additionally, the message page is not a mere logging window, but receives the messages and notices for the currently executed query (we already have a logging mechanism...). That's why it has to be cleared before each execution. The query being executed is in the query page, so why repeat it? If you're repeatedly executing many big queries, like I do, you won't see any more what's really important.
