In general, AWS RDS does not set shared_buffers in a manner similar to the community version. From the AWS documentation, the recommendation is to set it at 75% of the instance’s memory size. So, does the 8Gb that you’re requesting match the 75% recommendation? And if I’m not mistaken about this, you could use the database parameter group to set this to the 8Gb level without using any sort of calculation.

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
