Review comment:
`Seq("!=", "<>", "between", "case")` appears many times, shall we put it in
```
object ShowFunctionsCommand {
// operators that do not have corresponding functions.
// They should be handled in `DropFunctionCommand` as well.
val virtualOperators = Seq("!=", "<>", "between", "case")
}
```
