> When I added parsing/validation for PERCENTILE_CONT/DISC in CALCITE-5564, I required an {{OVER}} clause to be used, because this is what BigQuery currently allows. However I think it would be nice if Calcite extended what these functions are capable of by allowing them as either window functions *or* aggregate functions.
> The change itself would be simple enough, I have a draft commit I can put up after this.
> As an example, the below query is current invalid (because it is missing an OVER()), but would be valid after my change.
> {{SELECT PERCENTILE_CONT(age, .5) FROM users}} (this would return a single row instead of a row for each row in the table.)
