After running the transaction alters, run
the dbverify script. To prevent dbverify from
generating "IndexAdds" SQLs for dropped indexes, ensure that the dropped
indexes are listed in the <INSTALL_DIR>/extensions/schemagenerator/indexes_not_created.txt file.
Or, if the INDEXES_NOT_CREATED property in the <INSTALL_DIR>/properties/sandbox.cfg file
is configured, add the list of dropped indexes to the file referenced
by the property.
Execute the SQLs generated by the dbverify script
in your database.
