Hi, our developers use a ORM tool which generates updates that write all columns of a table. In most cases, however, very few columns actually change. So, those updates mostly write the same value that already is there in the column.
Now, if there is an index on such columns, does Postgres recognize the situation and skip the index update? Similarly, does it skip the FK or UNIQUE check?
