Hi,

    Previous versions also modified import_fetched_statistics()->import_attribute_statistics()
by adding the most_common_vals_kind parameter.

   However, when analyzing a PostgreSQL FDW, for example with ANALYZE simport_ftable;
in contrib/postgres_fdw/sql/postgres_fdw.sql, fetch_attstats() did not retrieve the
corresponding MCV kind to pass to the newly added most_common_vals_kind parameter.
This issue is now fixed.


regards,
