Review Comment:
I don't whether it works or not, but something like this?
```scala
def quoteIfNeeded(part: String): String = {
if (part.matches("[a-zA-Z0-9_]+") && !part.matches("\\d+")) {
part
} else {
s"`${part.replace("`", "``")}`"
}
}
def quote(parts: Seq[String]): String = {
parts.map(quoteIfNeeded).mkString(".")
}
def getDatasourceV2Identifier(plan: LogicalPlan): Option[TableIdentifier]
= {
val identifier = getFieldVal[Option[AnyRef]](plan, "identifier")
identifier.map { id =>
val namespaces = invoke(id, "namespaces").asInstanceOf[Array[String]]
val table = invoke(id, "name").asInstanceOf[String]
TableIdentifier(table, Some(quote(namespaces)))
}
}
```
