Plan weirdness. A sort produces more rows than the node beneath it

Hello,

I'm trying to understand a bit of weirdness in a plan output. There is a
sort node above a sequential scan node where the scan node produces 26,026
rows yet the sort node above it produces 42,995,408. How is it possible to
sort more data than you received?

The PostgreSQL version is 14.2 running on Amazon's RDS. Thanks.
