Large number of partitions of a table

Dear Colleagues,

Do you have success (or disaster) stories for having a large number of
partitions in a table (like maybe 10000) in a production database?

I've found a great article
https://www.depesz.com/2021/01/17/are-there-limits-to-partition-counts/
and basically it says 70000 partitions are OK but would like to hear
more opinions especially from production experience.

If a table itself has e.g. 50 indexes, partitioning it will create 10000
extra tables and 50*10000=500000 indexes, isn't it a heavy burden on the
system catalogs (pg_statistic etc). It may slow down ANALYZE or have
some other adverse effects.

Any comments welcome.
