newsysviews - newsysview: lots of new stuff: - "relations" views

Log Message:
-----------
lots of new stuff:
- "relations" views generalizing existing tables/views stuff
- sequences view
- table_storage view with breakdown of main/toast/index sizes
- tablespaces and tablespace contents
- schema contents

fixed incorrect handling of tablespaces in existing views; correctly handle
0 in pg_class.reltablespace as meaning "database's tablespace" rather than
just leaving it null.
