Hi Everybody,

I am searching for a pg_xxxxx view that would allow me to view the
properties of an index.
- the fillfactor it was created with
- the amount of free space on a page(s) storing the index ( assuming
that it was created with a fillfactor and the index has incurred updates
since the creation taking up some space reserved by the fillfactor
during the load).

The usage of a fillfactor nor fragmentation info does not get displayed
in pgAdminIII. In SQL Server 2005 the analogous views would be:
Obcc showcontig and sys.dm_index_physical_stats

Perhaps there is another way to determine fragmentation of indexes in
Postgres, any hint would be much appreciated.

Sincerely,
Kasia
