Add pinning_backends column to the pg_buffercache extension.
The new column shows how many backends have a buffer pinned. That can
be useful during development or to diagnose production issues
e.g. caused by vacuum waiting for cleanup locks.
To handle upgrades transparently - the extension might be used in
views - deal with callers expecting the old number of columns.
