How many cores do you have on the system? What sort of storage
systeme? What, exactly, are the symptoms of the problem? Are there
200 active connections when the problem occurs? By "active", do you
mean that there is a user connected or that they are actually running
something?

If you want to handle a large number of clients concurrently, this is
probably the wrong way to go about it. You will probably get better
performance with a connection pool.

Depending on your workload, a Linux machine with 32GB RAM should
probably have this set somewhere between 1GB and 8GB.

Making VACUUM less aggressive usually backfires and causes
unacceptable performance, although that might not happen for days or
weeks after you make the configuration change.
By the way, the software is called PostgreSQL. It is often shortened
to Postgres, but "Postgre" is just wrong.
