Azure-specific notes

The default value for the max_connections server parameter is calculated when you provision the instance of Azure Database for PostgreSQL flexible server, based on the product name that you select for its compute. Any subsequent changes of product selection to the compute that supports the flexible server don't have any effect on the default value for the max_connections server parameter of that instance.

Every time you change the product assigned to an instance, you should also adjust the value for the max_connections parameter according to the values in the following formula.

In virtual machines with up to 2 GiB of memory, the formula used to compute the value of max_connections is memoryGib * 25.

In virtual machines with more than 2 GiB, the formula used to compute the value of max_connections is MIN(memoryGib * 0.1049164697034809, 5000).

Based on the previous formula, the following table lists the values this server parameter would be set to depending on the amount of memory provisioned:

Memory size max_connections

4 GiB 429
8 GiB 859
