To make it easier to understand, update the explanation for scenarios with high space usage, noting that these scenarios include, but are not limited to:
The overuse of database space caused by the accumulation of system WAL logs is caused by the failure to consume/clean the logical replication slot in time, and a large amount of data additions and deletions in a short period of time.
SQL is more complex, which causes the temporary space of the system to skyrocket, resulting in excessive database space utilization.
