PostHocResolveUpCast

case class PostHocResolveUpCast(spark: SparkSession) extends Rule[LogicalPlan] with Product with Serializable

Post-hoc resolution rules PreprocessTableMerge and PreprocessTableUpdate may introduce new unresolved UpCast expressions that won't be resolved by ResolveUpCast that ran in the previous resolution phase. This rule ensures these UpCast expressions get resolved in the Post-hoc resolution phase.

Note: we can't inject ResolveUpCast directly because we need an initialized analyzer instance for that which is not available at the time Delta rules are injected. PostHocResolveUpCast is delaying the access to the analyzer until after it's initialized.
