You should have read carefully what I wrote. 1000 is not an upper limit. 1000 partition is the number after which performance starts dropping . There is a blog in www.timescale.com which also highlights the same.

We are hearing around a thousand, is that a limit. Do we have plan to increase the number of partitions for a table. We would appreciate if somebody can help us with this?
