Question

周末，我的postgresql服务器停止运行。经过一些故障排除后，我意识到我在1 TB驱动器上的空间不足。我有办法从中恢复过来吗？

我没有空间暂时移动文件。删除中的任何一个都是安全的吗？
使用Postgresql 10设置逻辑复制 - 我可以调整这些设置以防止再次发生这种情况吗？

/ pg_replslot = 395 GB

/ pg_wal = 283 GB

wal_level = logical                     # minimal, replica, or logical

# - Sending Server(s) -

# Set these on the master and on any standby that will send replication data.

max_wal_senders = 3             # max number of walsender processes
                                # (change requires restart)

#wal_sender_timeout = 60s       # in milliseconds; 0 disables

max_replication_slots = 4       # max number of replication slots

由于wal文件而空间不足
