update behavior

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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?
