      Description

      There are a significant number of cases where codegen is disabled in the aggregation node: UDAs, timestamps, some string functions.

      The root cause for these was that codegen support for aggregate functions using the UDA interface was only half-completed. Most of the infrastructure is there, it just needs to be used and tested.
