Another amazing release, congrats to all the contributors. There are simply too many things to call out - just a few highlights:

Massive improvements to vacuum operations:

    "PostgreSQL 17 introduces a new internal memory structure for vacuum that consumes up to 20x less memory."

Much needed features for backups:

    "pg_basebackup, the backup utility included in PostgreSQL, now supports incremental backups and adds the pg_combinebackup utility to reconstruct a full backup"

I'm a huge fan of FDW's and think they are an untapped-gem in Postgres, so I love seeing these improvements:

    "The PostgreSQL foreign data wrapper (postgres_fdw), used to execute queries on remote PostgreSQL instances, can now push EXISTS and IN subqueries to the remote server for more efficient processing."
