Обсуждение: pgsql: Fix possible logical replication crash.

Fix possible logical replication crash.

Commit c3afe8cf5a1e465bd71e48e4bc717f5bfdc7a7d6 added a new
password_required option but forgot that you need database access
to check whether an arbitrary role ID is a superuser.

Report and patch by Hou Zhijie. I added a comment. Thanks to
Alexander Lakhin for devising a way to reproduce the crash.
