Re: Extended Statistics set/restore/clear functions. - Mailing list pgsql-hackers

hi.

v12-0001 and v12-0002 overall look good to me.

        if (dependency->nattributes <= 1)
            elog(ERROR, "invalid zero-length nattributes array in
MVDependencies");
This is an unlikely-to-happen error message,  but still, “nattributes”
seems confusing?

in  doc/src/sgml/func/func-json.sgml, we have \gset
<programlisting>
SELECT '{
.......
  }
}' AS json \gset
</programlisting>

similarly, in doc/src/sgml/perform.sgml, I think the query should be:

SELECT stxkeys AS k, jsonb_pretty(stxdndistinct::text::jsonb) AS nd
  FROM pg_statistic_ext join pg_statistic_ext_data on (oid = stxoid)
  WHERE stxname = 'stts2'    \gx
