> # mysql flumenewresearch < upgrade-0.6.0.mysql.sql
> ERROR 1071 (42000) at line 16: Specified key was too long; max key length is
> 767 bytes
> {code}
> Here's the cause of the problem from upgrade-0.6.0.mysql.sql:
> {code}
> ...
> ALTER TABLE `COLUMNS` MODIFY `TYPE_NAME` VARCHAR(4000);
> ...
> ALTER TABLE `COLUMNS` DROP PRIMARY KEY;
> ALTER TABLE `COLUMNS` ADD PRIMARY KEY (`SD_ID`, `COLUMN_NAME`);
> ...
> {code}
> We need to make sure that the PK on COLUMNS.TYPE_NAME is dropped before the
> size of the column is bumped to 4000.
