Tom Lane 7148050105 Give a better error for duplicate entries in VACUUM/ANALYZE column list. ... Previously, the code didn't think about this case and would just try to analyze such a column twice. That would fail at the point of inserting the second version of the pg_statistic row, with obscure error messsages like "duplicate key value violates unique constraint" or "tuple already updated by self", depending on context and PG version. We could allow the case by ignoring duplicate column specifications, but it seems better to reject it explicitly. The bogus error messages seem like arguably a bug, so back-patch to all supported versions. Nathan Bossart, per a report from Michael Paquier, and whacked around a bit by me.
