Perf-Test: Database begin transaction failed: pq: too many clients already

[dechdev]

During a performance test of broadcasts at 50 tx/sec, the following two database errors were encountered ~4.5 hours into the test:

• ERROR SQL query failed: pq: sorry, too many clients already
• FF10114: Database begin transaction failed: pq: sorry, too many clients already

This causes the POST /messages/broadcast requests to not be handled at full capacity and returning 500 status codes
