Hello.

As you may know, RDS metrics do not include metrics related to slow queries.  
So, enable query logging for RDS PostgreSQL and change "log_statement" to 1 in the RDS parameter group.  
Also, by setting the value of "log_min_duration_statement" to 5000, queries that take more than 5 seconds to execute will be output to the log.  
Please set the type of query you want to output to the log with the value of "log_statement".

After outputting to CloudWatch Logs, you can create metrics by using a metric filter, etc., and then you can create alarms.
