这很可能是一个损坏的索引。需要有人删除或修复重复的条目。[如何使用 amcheck 检查 PostgreSQL 索引完整性（损坏）](https://meta.discourse.org/t/how-to-use-amcheck-to-check-postgresql-index-integrity-corruption/153207)可能会有帮助。另请参阅 [https://meta.discourse.org/t/cant-restore-due-to-corrupt-indexes-with-some-clues-on-how-to-deal-with-corrupt-indexes/137400。](https://meta.discourse.org/t/cant-restore-due-to-corrupt-indexes-with-some-clues-on-how-to-deal-with-corrupt-indexes/137400%E3%80%82)
