Andres Freund	f57791985a	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. Reviewed by Fujii Masao and Rajeev rastogi.	12 years ago

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.
