Because otherwise there would be tons of rows in each
partition, and randomly "updating" the index for that many
rows 2000 times per second isn't doable (the indexes
get so big that it would be like writing a multi-GB file
randomly)

I would create the table with all the indexes already in; but only

the index related to the "current timestamp of the inserted row"
would be updated; the others wouldn't be touched.
