Hi Tim,
Yeh datatype is even not supported right now. As tenantId is numeric and
encryption/decryption would go through text/bytea , so even tougher to
encrypt that column data.

Hi Guyren,
Yup right now data is being accessed in this manner only.
application access using tenant user only who have specific tenantId in
that session and can see its own data only. It doesn't know about anyone
else's data and neither can get/fetch.
So isolation is 100% guaranteed right now.
An interesting option is to make your tenants work through views, and have the
views work through a variable that contains the tenant’s id. There would be a
bit of coding, but it would be the same for every table, so you could automate
it easy enough.
When you’re done, client software just sets

The below are the scenarios which we are dealing with.

We are using Postgres 12.2.1 for fetching per minute data for about 25
machines but running parallely via a single thread in python.
But suddenly the insertion time has increased to a very high level, about
30 second for one machine.
We are in so much problem as the data fet
