I understand what you're saying. However it's not the amount of messages per day. I have cycle set on the sequence so that when it reaches the limit it will start back at 1 again. If however some users still have messages in their accounts that have used random ids from 1 onwards postgresql will produce the error that it's trying to insert a duplicate id that already exists, so in theory I want the system to run for infinity. I hope this makes sense. Thankyou for your time.
