Check whether the target database user conflicts with the source database user.
In full database migration, if the target database has the same account as that in the source database, you need to delete it.
create user new user with password 'password'; grant pg_tencentdb_superuser to new username; alter user new user with CREATEDB; alter user new user with CREATEROLE;
After the conflicting user is deleted, run the verification task again.
drop user conflicting user; # If the conflicting user has resource dependencies, run the following statement to modify the owner of the resources first (with a table as an example below): alter table table name owner to new user;
