Review Comment:
The `catalog` meaning in Database(MySQL) is different with `catalog` meaning
in Flink SQL, we'd better make it more clear, we can refer other popular
projects as well. Eg we can use `database` as parameter name and add proper
java doc, because `database` == `catalog` in Postgresql and MySQL 8.0.x.
