Now, today's activity is particularly interesting because we're looking at five standalone commits that really showcase the thoughtful, incremental improvements that make PostgreSQL such a solid choice. No massive feature drops today, but trust me, these changes are going to make your life easier.
Let's start with the star of today's show - a brilliant optimization from Masahiko Sawada that's going to save you serious time if you're working with logical replication slots during upgrades. You know that feeling when pg_upgrade seems to take forever checking all your logical slots? Well, Masahiko just made that…
Here's what was happening: every time you upgraded with multiple logical slots, PostgreSQL was checking each slot individually to make sure they'd all caught up with their WAL records.
