你说得对，这是之前的错误：
ERROR: could not create unique index "index_tags_on_lower_name"
DETAIL: Key (lower(name::text))=(زبا�) is duplicated.
EXCEPTION: psql failed: DETAIL: Key (lower(name::text))=(زبا�) is duplicated.
我想这已经在以下链接中报告过了：Can't restore due to corrupt indexes (with some clues on how to deal with corrupt indexes) 和 There are some duplicated tags due to database corruption and I can't merge
