explain (verbose, verbose off, analyze on, analyze off, analyze on)
I would just update this paragraph to note the last one wins behavior.
"When the option list is surrounded by parentheses, the options can be written in any order. However, if options are repeated the last one listed is used."
I have no desire to introduce breakage here. The implemented concept is actually quite common. The inconsistency with COPY seems like a minor point. It would influence my green field choice but not enough for changing long-standing behavior.
