Hello All,
Is there any way in postgres to have an aggregate that uses input from two
columns without using composite types? The example we are working on is a
first or last aggregate which requires a data value and a date column. The
result would be to find the latest date within the group and return the
associated data value. Since there may be multiple date columns each with
dependent columns, we can't use a sort by date and a simpler first or last
aggregate.
Thanks,
-Chris
