It turns out there's a handy feature in PostgreSQL called row constructor comparisons that allows me to compare tuples of columns. That's exactly what we need. Instead of doing CreateAt > ?1 OR (CreateAt = ?1 AND Id > ?2) , we can do ( CreateAt, Id) > (?1, ?2) . And the row constructor comparisons are lexicographical, meaning that it's... See more

Learning: what aspect of my nervous system (emotion, perception, sensations) am I trying and are available to change? How to structure the change?

Data bases have gotten so good at this, that the term is almost misleading now. “Base” suggests something rigid, without which the data would slip away.
