I'm not sure what the security problem would be for allowing non-superusers
to run pg_is_xlog_replay_paused(). And if there are none, there is no
reason why the function should be restricted like that.
Also, looking at that specific documentation page, ISTM it needs a better
way to show which functions actually *do* require superuser privileges. In
some groups it states which do require it, and in some where it doesn't.
Perhaps we should add a column to each of the tables with a yes/no value
indicating if superuser is required for that specific function? Or at least
have every table be prefixed by a statement saying which require superuser.
