I don't understand. It's somewhat more difficult to grab all the
primary keys of the currently-selected items (and you can put a
Javascript button with "select all in this page"), this I concede. But
how is it better to be unsure if you are really deleting what you want
to delete? Suppose another admin is also deleting and the LIMIT/OFFSET
shifts between the time the page is presented and the button "delete
these" is pressed...
"Hey, PostgreSQL is stupid," they'll say. "How can they offer such an
unsafe misfeature."
