Cleanup phase: You can delete the encrypted table, column key, and master key in sequence. Preparation Phase If you use the encrypted database for the first time, you need to perform the preparation. The next time you use the database, you can skip this phase.
Cleanup phase: Delete the encrypted table, column key, and master key in sequence. Master Key Generation Phase When you use an encrypted database for the first time, you need to use an external key manager to generate at least one master key.
Delete the sensitive information in a timely manner. You can also set process-level environment variables using the standard library API.

If there are residual files of soft links for the tablespace in the data directory, delete the residual files, and then perform O&M operations. CREATE TABLESPACE cannot be used for two-phase transactions. If it fails on some nodes, the execution cannot be rolled back.
This parameter is used for the mechanisms to verify the primary-standby relationship and delete WALs. This is a SIGHUP parameter. Set it based on instructions in Table 1.
