Differ from MySQL, this is changed to revered keyword?

[zimulala]

MySQL does not currently support vector keys: link.
Indexing-related keywords such as fulltext and unique are reserved, so this is also done here. In addition, it is a little complicated to process without a reserved word.

[zimulala]

PM(@joey-yez ) comments that if it is used as the reserved keyword, there will be compatibility. So I will update it.
