By external, I mean with a separate distribution, which is the result if
the addition is rejected. I could try to submit to contrib, but the
current status is that part is that it should be "reduced" or even
disappear, so I'm no that confident that it would be accepted either.

If you are a user and you need a bit_*, then you look in the doc. In the
aggregate function documentation, you'll find no such function, so then
you turn to the "how to add an aggregate function". Things there are very
interesting, but it is a little bit overshot for a simple basic aggregate.

Have a nice day,
