Ever since PostgreSQL 11 we have JIT (Just-In-Time compilation).
Information about JIT is displayed in explain analyze plans, but up to this moment, explain.depesz.com didn't display it properly. But not anymore. Thanks to release 1.05 of Pg::Explain and subsequent change in templates for the site, you can now see nice JIT info.
Hope you'll find it useful 🙂
Over the years I saw some people find themselves in position where they have to start dealing with PostgreSQL with minimal, or none, prior exposure. This leads to problems with seemingly easy tasks – how to change config? How to find stuff in logs?
So I decided to write some blogposts to be able to point such people to pre-made tutorials.
And I start today, with information on how to find PostgreSQL config files.
Every so often, on irc, someone asks if they can remove postgres database, and why is it even there.
Figured I can write one blogpost to answer it once and for all, and use it as ready answer whenever the question resurfaces.
On 1st of February 2021, Peter Eisentraut committed patch:
SEARCH and CYCLE clauses This adds the SQL standard feature that adds the SEARCH and CYCLE clauses to recursive queries to be able to do produce breadth- or depth-first search orders and detect cycles. These clauses can be rewritten into queries using existing syntax, and that is what this patch does in the rewriter.
