Azure PostgreSQL 突然使用所有存储

Question

昨天，我一直在追加的 'Azure Database for PostgreSQL server' 数据库突然增加了它的增长率并用完了所有存储空间，并且脚本报告了错误，因为连接变为只读。

磁盘上数据库大小的查询加起来不像 18GB

    select pg_size_pretty(pg_database_size('database_alpha')) => '80 MB'
    select pg_size_pretty(pg_database_size('database_beta')) => '458 MB'
    select pg_size_pretty(pg_database_size('postgres')) => '8645 kB'

如果不是我的数据库，什么可能在使用存储，我如何防止它在未来发生？

查看日志，下午 5 点左右开始出现很多类似于以下内容的条目：

Answer 1

我猜是硬件故障阻止了它写入 WAL 并且正在使用 space，它现在似乎已经恢复：
