Re: Increase the size of shared_buffers in AWS RDS 10.11 postgreSQL

Hi John,

Yes, I calculated as per pgtune(https://pgtune.leopard.in.ua/#/)

 advisor. I took 25% of physical memory 32GB in AWS RDS PostgreSQL which is 8GB. 

AWS PostgreSQL Configuration: -

 

How to update the shared_buffer into 8GB in the AWS RDS Parameter Group here below?

Thanks & Best Wishes,

Ashok

Hi All,

I want to increase the size of shared_buffers in AWS RDS postgreSQL 10.11.  When I see it in the DB parameter group in AWS it says "SUM({DBInstanceClassMemory/12038},-50003)"  and at the instance level I see 2694408 .

Please let  me know how to calculate and  change the value for 8GB?

 

 

Thanks & Best Wishes,

Ashok
