Subject: [PATCH v3 1/3] Add tableid and attnum columns to pg_stats.

The primary purpose of this patch is to expose the starelid column of
pg_statistic in the pg_stats view. Having this available will allow us
to simplify some code in pg_dump which currently has to store arrays of
nspname+relname in order to fetch a resonable amount of statistics in
one query. Furthermore, the query used in pg_dump requires a redundant
qual in the WHERE clause to ensure that it uses a specific index, thus
avoiding a hash join and the expensive sequential scan of pg_statistic
that that entails.

Additionally, there have been times when it would have been nice to have
attnum as well as attname available.
