Error in PostgreSQL connection: Error { kind: Closed, cause: None }

Hi Prisma Team! My Prisma Client just crashed. This is the report:

We get batches of these (and have been for many months, maybe once a week), where something will die and then we’ll lose all DB connections for about 25s. At first we thought it was a max number of connections or CPU issue, but we don’t see much evidence of that being the case.

I recognize it’s possible this is a Postgres or Render (our host) issue, but am hoping for some advice on eliminating Prisma’s engine as a cause/general debugging help, since Render has not seen this issue before with their setup.

We’ve tried playing with max connections (currently connection_limit=5 on each of our 2 machines), which hasn’t changed anything.
