Yes, it is little bit annoying but I like it. You don't need any index
on parent table but you have to create them "manually". I wrote simple
python script which creates partitions and required indexes in advance
(tables are partitioned by date).
I like the flexibility because you can have different indexex on
different partitions. For example, I discovered that adding index will
improve several queries. In the production I can't afford exclusive
lock (build index concurrently takes ages) so I updated and re-run the
script which re-created future partitions.
