PolarDB structure and privilege verification tool

PolarDB introduces a new structure and privilege verification tool. After migrating from Oracle to PolarDB for PostgreSQL (Oracle compatible), you can use this tool to compare the object structure and the users, roles, and privileges between the destination cluster and the source Oracle database. Two HTML reports are generated to help you locate and close the gaps by using their tabs, comparison status, and filters.
