Add more columns to pg_stats, pg_stats_ext, and pg_stats_ext_exprs.

This commit adds table OID and attribute number columns to
pg_stats, and it adds table OID and statistics object OID columns
to pg_stats_ext and pg_stats_ext_exprs.  A proposed follow-up
commit would use pg_stats.tableid to simplify a query in pg_dump.
The others have no immediate purpose but may be useful later.

Bumps catversion.
