This commit adds columns in view pg_stat_subscription_stats to show the number of times a particular conflict type has occurred during the application of logical replication changes. The following columns are added: confl_insert_exists: Number of times a row insertion violated a NOT DEFERRABLE unique constraint. confl_update_origin_differs: Number of times an update was performed on a row that was previously modified by another origin. confl_update_exists: Number of times that the updated value of a row violates a NOT DEFERRABLE unique constraint. confl_update_missing: Number of times that the tuple to be updated is missing. confl_delete_origin_differs: Number of times a delete was performed on a row that was previously modified by another origin. confl_delete_missing: Number of times that the tuple to be deleted is missing. The update_origin_differs and delete_origin_differs conflicts can be detected only when track_commit_timestamp is enabled.
