When I checked for the Amazon Redshift error connection limit "498" exceeded for non-superusers, I see that a few AWS Lambda functions are establishing database connections to Redshift databases but not closing the database connection after they finish their tasks. But when it comes to database connections there is not a solution which is so effective to drop unused database connections. To view a list of users, query the PGUSER catalog table. To change a user, for example changing a password, use the ALTER USER command. To remove an existing user, use the DROP USER command. To create a superuser, use the CREATE USER command with the CREATEUSER option. Garbage collectors are used to remove unused objects from memory. To create a user, use the CREATE USER command.

The outcome of the above SQL query shows that especially one of the database users has an excessive number of database connections open.
