I think you have not read the documentation about FOR UPDATE and LIMIT
on the SELECT reference page:
Well, I did, but I clicked the link to Chapter 13 before scrolling down

Hi. I have a large table that has a modify_date field in it, which is
timestamp without time zone.
I used to be able to do queries like these in 8.2.3 --

1;

select id from users where modify_date::date =
