The user *will* get a similar HINT if they happen to *also* spell the
would-be ambiguous column name slightly incorrectly:
ERROR: column "barr" does not exist
LINE 1: ...lict (bar) do update set bar = excluded.bar where barr != 5;
^
HINT: Perhaps you meant to reference the column "foo.bar" or the
column "excluded.bar".
