RE: Max# of tablespaces

I agree - it requires a re-think/re-build

As for oracle, quite easy to add tablepaces in flight, assuming you don’t hit max db_files

I was more curious if there was an actual defined limit - oracle stops at 64K , and their old application release would
have2tbsp per module, and at 400 or so that’s a hassle

It's a very common Oracle-ism to have a lot of tablespaces, in part because (IIRC) Oracle makes it an incredible pain
inthe neck to add tablespaces once the DB is in use.  For sharding purposes, you probably want schemas in PostgreSQL
insteadof tablespaces, although having that many schemas is going to not be optimal, either.
