The current test TestCassandraConnectorTest has some issues:

Unrelated types in a table
- It reduces maintainability when we want to add test cases to a type
The definition and data are managed in the different class
- We need to look for the different class when we want to check the expected values
Less coverage in a type
- Should test min, max, null
- Should test DST, juli

The .forall pattern is a great way to create an optional filter for a field that could be defined or not:

case class Person(name: String, age: Int)
val nameOpt: Option[String] = Some("Joe")
run { query[Person].filter(p => lift(nameOpt).forall(_ == p.name)) }
// SELECT p.name, p.age FROM Person p WHERE ? IS NULL OR ? = p.name
// (i.e. when nameOpt := None then the `WHERE ? IS NULL`

When using UNION, with ORDER BY or LIMIT within a subexpression's SELECT statement, PostgreSQL requires the SELECT statement be enclosed in parentheses: https://stackoverflow.com/a/24024639 However, the following QueryDSL code causes a syntax error against Postgres because it doesn't generate those parentheses:

val i = Item.syntax("i")
selectFrom(Item.as(i)).orderBy(i.id).u
