Seems to be fixed with this patch:

FIX: Multiple topics may have the same post as its solution (#348)

committed 02:21PM - 26 Mar 25 UTC

We are seeing some errors when migrating and adding indexes on `answer_post_id`.… ``` #<StandardError:"An error has occurred, all later migrations canceled:\n\nPG::UniqueViolation: ERROR: could not create unique index \"index_discourse_solved_solved_topics_on_answer_post_id\"\nDETAIL: Key (answer_post_id)=(13006) is duplicated.\n"> ``` This PR modifies the earlier migration, and also adds one before the addition of indexes to remove duplicates.
