PostgreSQL: Cleaning Up the Node Reading Internals
Today's commits center on making PostgreSQL's internal node-reading code safer and better organized, alongside a new SQL feature for aggregate planning and a couple of small correctness fixes. The common thread is long-term maintainability work on core infrastructure that most developers never touch directly, but that everything else depends on.

Good day, and welcome to PostgreSQL for August twenty-fourth.
The clearest pattern today is a cleanup effort around the internal machinery PostgreSQL uses to read and reconstruct nodes from text representations. Two commits from Michael Paquier, working with Matthias van de Meent, tackle this from different angles. Commit 9673a0a makes the string-to-node infrastructure…
Second theme: closing small gaps in existing features. Tom Lane's commit 8aa49d3 fixes an oversight from an earlier change that let planner support functions optimize aggregates, but gave extension authors no SQL syntax to actually attach one. Now CREATE AGGREGATE has a SUPPORT clause, and pg_dump and pg_upgrade…
A few smaller but worthwhile fixes rounded out the day. David Rowley's commit 53a981e corrects a test helper's math in test_bitmapset — no live bug, but the fix makes that test more effective and the parameter ordering more sensible. Daniel Gustafsson's commit 8646214 replaces a hardcoded buffer size in the backup…
What's next: expect more thread-safety groundwork as this pattern continues, and extension authors working with aggregates should look at the new SUPPORT clause.
That's the briefing for today.…
