使用渗透快照模式创建 osm-pbf 的 Postgres 数据失败

如何解决使用渗透快照模式创建 osm-pbf 的 Postgres 数据失败

我已经使用渗透快照模式将 pbf 导入到 postgres

现在想从该模式创建 pbf，使用以下命令

osmosis --read-pgsql host=localhost database=osmosisv1 user=postgres password=postgres postgresSchema=contry_snapshot validateSchemaVersion=no --dataset-dump --write-pbf C:\usr\share\osm.pbf

但得到以下异常

解决方法

正如你看到的异常，它清楚地提到了以下错误

比较方法违反了它的一般约定！

这是因为 Comparator 不是传递性的，有 ID Comparator 并且数据库中的 id 是随机生成的，所以随机生成的 id 给这个比较器带来了问题

"Comparison method violates its general contract!"
