PG17 failing tests (DST related?) - Mailing list pgsql-hackers

For about a week, the Windows builds I've been running in Github have been failing for PG17: https://github.com/dpage/winpgbuild/actions/workflows/postgresql.yml. The consistently failing tests are:

postgresql:recovery / recovery/027_stream_regress
postgresql:pg_upgrade / pg_upgrade/002_pg_upgrade
postgresql:regress / regress/regress

which all appear to have the same failure in jsonb_jsonpath:

It seems likely this is related to the DST change in the US, as the issue started occurring on 4th November.
