Postgres instance type modify

Question

Hi,

I would like to use an instance like db.t4g.medium for Postges 16, but currently the smallest I can go is with a db.m6g.large which is too large for my needs. How can I do that?

Thanks,

it's available for Deployment options - Single DB instance

If you are doing this in the RDS console, you'll need to choose "Burstable classes (includes t classes)" to get the instance types in the t* families to show in the menu.

Hello,

According to this documentation, db.t4g.medium instance class must be available for all PostgreSQL 16, 15, 14, and 13 versions; and 12.7 and higher 12 versions, https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/Concepts.DBInstanceClass.html#burstable-inst-classes

I believe deployment options must be Single DB instance or Multi-AZ DB instance and not Multi-AZ DB Cluster.
