AWS RDS Free tier applies to db.t2.micro
This does not show for Postgres, so that means there is no rds free tier for postgres? Am I missing something?
I also checked "Include previous generation classes" and got nothing.
Switched to MySQL to see that it has db.t2.micro...Although I don't have a MySQL database.
Meaning I need to pay for db.t3.micro on RDS Postgres

The free usage tier for RDS does include 750 hours of usage per month, but it's for single-AZ Micro instance hours, not any of the larger instances. The micro instance normally costs $0.025/hour. The included storage is single-AZ without provisioned IOPs.
The AWS web site is pretty clear on what is included in the free tier.
If you haven't tried contacting AWS support, you should, They may be able to help you.
I had exact situation of 700$ and even after suspending my account I was being billed hourly as I had not terminated the RDS instances, but I called up aws customer support at 1 (888) 280-3321 and explained the scenario and it was an honest unintended mistake from my side as I had used extra large multi A Z RDS instance instead single with free tier. Amazon was kind enough to wave off as gesture of good will and provided me video tutorials which would help me understand better.
From the AWS documentation:
750 hours of Amazon RDS Single-AZ db.t2.micro Instance usage running MySQL, MariaDB, PostgreSQL, Oracle BYOL or SQL Server (running SQL Server Express Edition) – enough hours to run a DB Instance continuously each month
so if you run two instances, that will be a total of 1500 hours of usage, so you will be charged extra. But you can run one instance for free each month. Note that the RDS instance is part of the 12 months free tier in AWS. That means that this offer only holds for 12 months after creation of your AWS account.
I created an AWS account and use it for several years now. Now, I was experimenting with the RDS instance (free tier) and this started to change me.
So, I believe that the free tier is only free within 12 months of the AWS account creation.
CHECK DAILY THE AWS ACCOUNT, I had another mistake earlier that cost me $300 for that.
