It seems very unlikely to be a bug in postgres. I can't reproduce it on either
latest minor version for pg 15 or on HEAD. Have you checked in
pg_stat_activity and/or pg_locks why the query is waiting on? Maybe you have
some other extension or are using a fork that's responsible for this behavior?
In any case, the version 15.1 is missing 3 minor versions, so about 9 months
worth of bug fixes. You should start by updating to 15.4 first and see if you
still have the problem.
