go - What happens when defer is called twice on same variable?

Question

What happened when defer called twice when the struct of that method has been changed?

For example:

rows := Query(`SELECT FROM whatever`)
defer rows.Close()
for rows.Next() { 
  // do something
}
rows = Query(`SELECT FROM another`) 
defer rows.Close()
for rows.Next() {
  // do something else
}

which rows when the last rows.Close() called?
