Issue with not closing DB connections

See original GitHub issue

Bug description

I have a heroku free tier DB and it looks like Prisma is not ending connections after making calls to the hosted DB on heroku.

I am only using my app in basic development, and have never experienced any problems with too many connections, however, now I experience this error every few errors, and it persists even after killing all connections manually.

"[GraphQL]  Invalid  invocation:     Error querying the database: db error: FATAL: too many connections for role

How to reproduce

Steps to reproduce the behavior:

Create Heroku free tier postgresql DB
Make some queries involving joins across a few tables
See error of max connections being reached

Expected behavior

DB connections should be killed after requests are complete

Environment & setup

We now have a dedicated section in the docs for this situation: https://www.prisma.io/docs/concepts/components/prisma-client/working-with-prismaclient/instantiate-prisma-client#prevent-hot-reloading-from-creating-new-instances-of-prismaclient

Please let me know, if that doesn’t solve it for you, then we can reopen this issue.
