I think you're connecting to a patched server with an older version of
psql, so it doesn't know the catalog column was renamed.

pg_dump and pg_upgrade don't have that problem because they throw an
error when connecting to a newer server.

But for psql, that's perfectly reasonable to connect to a newer server.
Have we dropped or renamed catalog columns used by psql backslash
commands before, and if so, how do we handle that?

I can just not rename that column, but that's a bit frustrating because
it means I'd need to add a new column to pg_database, which seems
redundant.
