There is some sort of resource constraint preventing Postgres from
handling all its requests.
So:
Do you have any additional extensions/modules installed in Postgres?
What are the hardware specifications for the machine, memory, CPU,

What is the work load on the Postgres server?
What does the system show for load during this time?
What do the system logs show?
