I can second this behavior. We did a few things to mitigate the issue. HA may be at play here too.
We're still monitoring.
13.11 + HA - these issues
13.6 , no HA - no issues

Subject: [EXTERNAL] BUG #18141: sorry, too many clients error occurring very frequently
The following bug has been logged on the website:
Bug reference: 18141
Logged by: Ravi Agrawal

PostgreSQL version: 13.11
Operating system: RHEL
Description:
Hi Team,
We have updated PostgresSQL from version 13.4 to 13.11 and observing 'sorry, too many clients' error very frequently.
Connection count is shooting up on performing basic operations and crossing the max_connections value. This has not
beenobserved previously on Postgres
v13.4
We need to understand if this issue is caused due to the change in version.
Is there any history of known incidents facing this issue with the specific version of PostgreSQL.
Appreciate your response on this.
Many Thanks,
Ravi Agrawal
