I believe that if I UPDATE a row with the same values that it already has, this still dirties pages, writes the row, generates a WAL entry. There is no shortcut in the processing that's "hey, there's not really a change here, we'll just leave storage alone".
Is this correct?
Correct. You need a trigger to prevent the update. There is one provided: suppress_redundant_updates_trigger()
