Dear hackers,
Do you think there would be any use for an aggregate which returns an
array of the aggregated (usually simple) type? Has this already been
done by anyone? I looked at the source and noticed that for each
inserted item, the array utility functions perform a deep copy of the
entire array (plus a reallocation). Normally, this is no big deal,
but if executed in the query stage, it could be kind of slow. I also
noticed that null values inside is an item on the todo list. Is
anybody currently working on this?

I got another question to this:
why does PostgreSQL support Arrays in the first place?
For my taste, its a very messy concept...
