That seems like an orthogonal issue, not something that should be
bundled in this patch. IIRC we didn't reach a consensus on what to do
about the compression-leaks-information issue. One idea was to make it
configurable on a per-table basis, and if we do that, perhaps we don't
need to restrict access to pg_current_xlog_location() and friends.
