LKBEN11031: Howto prevent the error message "Sorry, too many clients..." under Postgresql
Symptom
You are working with postgres sql and get the previous message
Cause
You have reached the limit for database sessions which is 100 by default
Solution
You have reached the limit of database sessions. (default: 100) You need to increase the server's limit on how many concurrent backend processes it can start by changing the "max_connections" value in postgresql.conf and restarting the postgres server daemon.
Please do not "kill -9" the postmaster! This could damage your database. If it is unlikely that you reached this limit than you have to review your code and try to find out why the these processes are started all the time. In this case they might be idle.
