I think this is because of

https://git.postgresql.org/cgit/postgresql.git/commit/?id=8f388f6f554b113f25a53fe3237238d2c58ed1eb

We have this is release notes https://postgr.es/c/8f388f6f5


So, after upgrading to 17 (and thus, having this change), defaults
changed, some queries now need adjustment... I am not sure we have
fixable problem in HEAD here
