Alright, I'll pull it out. I see it's already been added to the
open-items list, so we shouldn't forget about it.
For my 2c, I'd much rather have the information restricted to a
privileged role instead of having to disable the feature. Further, all
tables need to be considered as having privileged information, not just
systems ones like pg_authid, as the user might not have rights on the
other columns or rows in the table.
Thanks!
