I have written an aggregate function which returns a "varlena" type whose
length is proportional to the number of rows passed to the function.
My question is what is the consensus on the best way to handle the case
where the input to the aggregate causes the length of the variable to
exceed the 8k limit? Abort the query? Generate an error message, and
discard subsequent data? Silently discard data? Something else?
