Whether that's worth it, or whether column name lengths would be too painful,

That is a good idea for simple cases, I'm just curious how it would look
like for more complex cases (you can have all kinds of expressions as
parameters for aggregate function calls).
If it works only for simple cases, I think it would be confusing and not
very helpful.
Wouldn't it make more
Hi,
A common annoyance when writing ad-hoc analytics queries is column naming once
aggregates are used.
Useful column names:
SELECT reads, writes FROM pg_stat_io;
column names: reads, writes
Not useful column names:
SELECT SUM(reads), SUM(writes) FROM pg_stat_io;
column names: sum, sum
