Can we add the tableid for now (see 0003) and follow-up with another
thread with the sql changes to pg_dump?
I also corrected v2-0001. The docs were still referencing "starlid"
instead of "tableid"

Subject: [PATCH v3 2/3] pg_dump: Use tableid in getAttributeStats
The existing query for fetching attribute stats is clumsy for several
reasons. One is that the volume of stats returned is unpredictable and
could be very large, so stats must be fetched in medium-sized batches.
The other is that the stats fetching query is on pg_stats, which
historically does not expose tableid, requiring us to pass in an array
of schemanames and an array of tablenames and unnest them in pairs. This
results in a hash join which gives very poor performance, but adding an
extra qual was able to trick the query into using an existing index.
That trick always seems brittle because it is, and while it works on all
past versions, there is no guarantee that it will continue to work on
future versions.
With that in mind, change the pg_dump query to instead use tableid on
versions in which tableid is available in pg_stats. This virtually
guarantees that pg_statistic will use index lookups, eliminates the
"trick" qual mentioned above, and is just simpler.

Subject: [PATCH v3 3/3] Add tableid column to pg_stats_ext and
pg_stats_ext_exprs
Same as dcccf721929, add a tableid column to pg_stats_ext and
pg_stats_ext_exprs. For now, this is done to be consistent with
pg_stats, but there could also be future cases where having the
OID of the table will be useful.

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.
