The CREATE DATABASE hang is indeed new in v15. The general dblink missed interrupt processing (e.g. pg_cancel_backend response delay) is an old bug.
Aha, that was what you were referring to! My apologies, was reading your mail a bit too quickly. :)
Commit d3c5f37 used the new functions for postgres_fdw, not just dblink. That caused message changes detailed in postgr.es/m/CAHGQGwGpDTXeg8K1oTmDv9nankaKTrCD-XW-tnkzo6%3DE9p5%3Duw%40mail.gmail.com so I'm inclined to omit postgres_fdw changes in back branches. postgres_fdw was already interruptible, so the point of making postgres_fdw adopt the functions was to reduce code duplication.
Makes sense.
Overall, in the absence of objections, I will queue a task to back-patch the non-postgres_fdw portion of commit d3c5f37 to v13-v16.
Thanks! Andreas
