I need to encapsulate, what are basically 2 related function calls into a single
function. The result of each of th calls is a date type.

y current thinking is to return a 2 row table with the 2 dates in it. But, I seem to
be having issues getting this to work.

Is it possible for a function to return a table with results from multiple
queries?

If the two queries are identical in returned columns you might be able to use UNION:
select f1.* from first_query as f1 UNION select f2.* from second_query as f2;

You can’t do any processing of f1 or f2.
