What about partitioning tables by tenant id and then maintaining

like a potentially more tolerable variant of #5 How many tenants are
we talking about? I gather partitioning starts to become problematic
when the number of partitions gets large.
I thought I had replied... Apparently I didn't.
The database can grow in two dimensions: The number of tenants and the
number of rows per tenant.
We have many tenants with relatively little data and a few with a lot of
data. So the number of tenants
is known ahead of time and might be 1000's.
