Thanks for the details. I understand it now. We do not use '=' in our
main slots-fetch query but we do use '=' in remote-validation query.
See validate_remote_info(). Do you think instead of doing the above,
we can override search-path with empty string in the slot-sync case.
SImilar to logical apply worker and autovacuum worker case (see
InitializeLogRepWorker(), AutoVacWorkerMain()).
thanks
