This table is massive but thankfully we fixed most of its complexities in previous patches. For MySQL/Sqlite: - Change type of rc_title and rc_source from "varchar binary" to "varbinary" - Drop default of rc_timestamp - Change rc_timestamp from varbinary(14) to binary(14) to standardize timestamp datatypes One index doesn't follow the uniform prefix rule but since it's in a maintenance script, will fix that in a follow up.
