10000 tables are there, because that's the number of partitions. And I'm
dropping them at the moment, because I'm doing testing. So it won't be
really crucial for production. But I still thought it was worth reporting.
Especially when the table dropping took .5 a sec.
The problem is that when I set up the shared_buffers say to 48G, the
timings of the tables rise significantly again.

Yes, before there was a strong reason to do that, now the timings are more
manageable, but maybe I'll implement that.
