How Do I Enable the Audit of INSERT, UPDATE, and DELETE Operations in GaussDB? How Do I Set the Maximum Number of WAL Sender Threads That Can Be Created in GaussDB? How Do I Set the Maximum Number of Bytes to Be Logged for Each SQL Statement in GaussDB?
Any DELETE on the same row will also acquire the FOR UPDATE lock mode, as will UPDATE that modifies values on the primary key column.
In this case, you need to delete the existing replication slot with the same name on the DN (if the replication slot is an LSN-based logical replication slot, you need to manually delete it on the corresponding node) and create a replication slot on the CN.

Global temporary tables can be created using ON COMMIT PRESERVE ROWS or ON COMMIT DELETE ROWS.
Delete dependent tables. DROP TABLE In GaussDB, CASCADE must be added to delete dependent tables. In MySQL, CASCADE is not required. Options related to table definition. CREATE TABLE ... and ALTER TABLE ...
int TEST_MODE_START_REPL = 2; // Test mode: Delete a logical replication slot. int TEST_MODE_DROP_SLOT = 3; // Enable different test modes.
A positive value indicates that the deletion information of temporary files whose size is larger than the specified value of log_temp_files is recorded. 0 indicates that the delete information of all temporary files is recorded. –1 indicates that the delete information of any temporary
